Gear Review: Fitbit Flex

Review by Michelle

I'm the Co-Founder of a mobile startup called Blink.

I know, you're wondering what this has to do with the outdoors. Absolutely nothing. Which is precisely why for Christmas this year I asked for a Fitbit Flex

Being a Co Founder of a mobile startup here in Silicon Valley means that I generally work 14 hour days, 7 days a week. And 99.9% of that time is spent sitting in front of a computer screen. For someone who enjoys living healthy, this puts quite a strain on exercise time.

I had been wondering for a while how little exercise I was getting, and began to think it was time I had a way to actually find out (rather than just optimistically guessing every now and then). Enter the Fitbit Flex.

I chose this over the myriad other wearables out there after careful research and based on several criteria:
  1. What it does
  2. How it looks & feels
  3. Price
  4. The company

What it does

My background is in Product Management, and that means I love data. Give me charts and graphs any day of the week. And the Fitbit gives me that in spades.

After pulling the Flex out of the box, I was guided through a very simple set up process in the Fitbit app. In just a few minutes I was up and running.

This app has been the real joy of the Flex to me. It's not only well designed, but it shows me at a glance every stat I could possibly want.

I can see the number of steps I've taken, how many miles I've covered, my total active minutes, calories burned, sleeping patterns, and also enter optional outside data like weight, calorie intake, and water consumption.

As part of set up, I set a goal for myself on how active I want to be. The app shows me every day a color-coded indicator of how I'm tracking against my goals. I can also tap on the wristband to see progress reflected with a series of lights when I'm on the go.

If I want more details, I can drill down into each category and look at a graph of exactly what I did and at what time. It's basically heaven for me.

One of the most surprising aspects for me has been tracking my sleep. By wearing the Flex to bed, I'm able to track the time I spend asleep, restless, and awake. Realizing just how little quality sleep I was actually getting was pretty eye opening.

How it looks and feels

The Flex came with a small wristband that is adjustable. I have very tiny wrists, and this is a constant concern when I buy watches and bracelets. I needed something that wouldn't slide around and annoy me all day.

Since buying it, I've been pleased to see that it's slim enough to be basically invisible under all but my tightest sleeved clothing. It's so inconspicuous that unless I point out to someone I'm wearing it, I've never actually had anyone remark on it.

It comes with one wristband to start (I got basic black), but there are several different colors of bands that you can change to including green, blue, red, and gray. This means I'll have plenty of fashion options. After all, you might as well look good if you're going to be wearing this every day.

I wear mine all day and most nights, and I've found it to be very comfortable. To remove dirt and oil though, I'd recommend washing the band itself with warm water and mild soap now and then. I generally do this while the tracker unit is out and charging.


At just under $100, the Flex was one of the more affordable of the wristband trackers out there. It's not the cheapest, but it's also far less expensive than what I considered to be the next best options.

The Company

I'd read a lot of great things about Fitbit as a company, and I certainly respected them as a fellow startup. For me, some of the best innovations I've seen come from smaller companies, and so I was more inclined to take my business to them that to Nike or Jawbone.

Although I know they've been through some recent growing pains on the Force, I can say I've been nothing but pleased with my Flex. 

So what's the verdict?

I'm almost 4 months into owning the Flex, and I can say I'm very happy with it. I think it's a well-made and incredibly useful product. It's serving as a daily reminder to me to stand up, walk around, and get exercising whenever I can. I've already recommended it to family and friends and several have purchased one and been just as pleased with the results.

I've still got a long way to go, but the enjoyment of seeing how far I actually have come (and the reminders when I occasionally fall behind) have been great thus far. I'm noticing that as I make better choices in exercising, I also make better eating choices.

All in all, it's been really satisfying to start feeling like I'm taking control of my health again, even if it's just a few steps at a time.

Gear Review: Salomon Comet 3D Lady GTX Hiking Boots

Recently, Robyn picked up a pair of Salomon Comet 3D Lady GTX boots for day hiking and the occasional overnight jaunt. If you would like to read about how she chose these boots be sure to check out the Beginner Hiking Series: Buying your first pair of serious hiking boots.

The Salomon Comet 3D boots are billed as a lightweight boot for long day hikes and overnight backpacking adventures. What they forgot to mention is that these are likely to be one of the most comfortable pairs of boots you will ever own. Salomon has clearly managed to take the great fit of their trail running shoes and transfer it into their boot lines.

The first thing you notice about these boots is that they are really great looking. Many women's boots on the market tend to be styled like a scaled down men's boot and are offered in colors that are questionable, to say the least. Robyn commented that these boots look like they were actually designed by a woman. The bright colors are there but understated. Many women's boot color pallets seem like a neon sign post designed to point out that they are in fact, made for women.

The dark shoe panels are nicely accented with purple

Robyn finally got to take them out this past weekend for a 10 mile day hike. At first, I was a bit skeptical these boots would provide a pain free first hike. While they are quite light, they seemed fairly stiff in the toe and midsection and I was worried Robyn would encounter the dreaded first hike blisters while breaking these in. Fortunately, there appeared to be a minimal, if any, break in period required and we got to see what a great pair of boots these really are.

Once on the trail, Robyn's first impression was that the Salomon Comet 3Ds are comfortable - really comfortable. Her description of the fit was that they were like "comfy Italian slippers" and that they felt really stable. To really run these boots through their first hike paces we chose a hiking trail loop with about 1000 feet of climbing and descending.

On steep downhill terrain the boots performed equally well on both loose and hard packed dirt. They provided plenty of grip and ankle support even on ground that was torn up by erosion gullies. The generous padding in the sole prevented any uncomfortable pressure points from developing and kept the impact fatigue to a minimum.

Despite the drought in California we managed to find a reasonably deep stream crossing. The boots had no issues crashing through the stream with water up to the top of the toe. The water rolled right off due to the Gore-Tex.

Going uphill is really where these boots started to shine. Robyn noted that the boots did not rub on her ankles at all and felt really light like a running shoe. She noted that she felt much more comfortable keeping her whole foot on the ground on really steep slopes rather than "toeing in" as many hikers with stiff boots tend to do.

10 miles down and the boots are feeling great.

The only real downside we found with these boots is that due to their dark color they can get somewhat warm. The ventilation is good, but in direct sunlight it just can't keep up fully with the amount of solar energy being absorbed by the large black panels. Wearing a thinner sock made for warm weather should easily mitigate much of this, and they are sure to be toasty in the winter.

After only a the first outings it is hard to evaluate the long term durability of the boots, but they seem well built. If Salomon's other shoes are any indication, they should last for at least a few years if not longer depending on the boot mileage and how well we care for them.

These boots turned out to be a fantastic surprise. They are genuinely one of the most comfortable women's boots on the market and at $200 are a great value.  We highly recommend them if you want your feet well cared for on your outdoor expeditions.

The Road to Whitney 2: Trails, Training and Gear

In this second installment of The Road to Whitney Series, I want to go into more detail about the Mountaineer's Route in preparation for both my solo single day trip and the overnight trip I am planning with my dad. In addition to the route, I will cover the training required and my training plan in more detail. And last I put together a preliminary gear list for both trips. If you missed it, be sure to check out The Road to Whitney 1: The Start of It All.

The Route

Route Overview
The Mountaineer's Route is the second most popular route for climbing Mt. Whitney; second only to the famed "Whitney Main Trail". In fact, John Muir made his first ascent of Mt. Whitney up what is today recognized as the Mountaineer's Route; the main trail had yet to be established. While the Main trail is a well marked and heavily maintained path leading all the way from Whitney Portal to the summit, the Mountaineer's Route is more accurately described as a use trail that extends about 60% of the way to the summit. The majority of the Mountaineer's Route is actually the North Fork Lone Pine Creek Trail and it is not until you reach main massif of Mt. Whitney itself that you are truly on the Mountaineer's Route. The North Fork Trail and Mountaineer's Route see significant traffic each year and are in no way hard to follow assuming you know where you are going. I still hear about a few people (OK, more than a few) each year who manage to get lost along the way and end up returning to the portal disappointed. In order to avoid such a fate, it is important to thoroughly study the route to ensure you take the proper path. Failure to stay on the correct line can result in you: getting lost, or worse yet, land you in a dangerous situation where difficult and technical climbing is required. So how do people get lost if there is a use trail? As I mentioned earlier, the use trail covers about 60% of the climb, with the remaining 40% being either off trail scrambling or climbing. Many people approach the Mountaineer's Route with little respect and assume (incorrectly) that it is as easy to follow as the main trail. But don't despair yet, as long as you know how to navigate to each major landmark and which line to take when you arrive, there is much less chance of getting lost. To help familiarize you with the major landmarks along the route, I will explain each difficult or technical section in detail. All of the major milestones and landmarks are indicated on the main map shown below.

The Mountaineer's Route

Major Landmarks

1. Main Trail Turn off
Both the Mountaineer's Route and the Whitney Main Trail leave from the Mt. Whitney Portal store and campground located above Lone Pine and both use the same trail head. However, once you set off, the turn off for the Mountaineer's Route is less than a mile up the trail so you will need to be on your toes. If you miss the sign, you will be in for some backtracking to regain the correct trail. Fortunately, this turnoff is outside of the permit zone so you won't be fined if you head too far up the main trail.

2. Ebersbacher Ledges
The Ebersbacher Ledges are the first major obstacle you will encounter along the route. The route up the ledges was pioneered in 1953 by Dale and Frances Ebersbacher as a way to bypass the thick and nearly impassable alder and aspen trees that choke the narrow canyon Lone Pine Creek follows. A more accurate description of hiking through the trees I have heard is that it is more akin to tunneling than walking. The ledges bypass requires you to scramble up a 3rd class rock flake and traverse along several narrow ledges that eventually switch back up to a larger ledge that allows you to walk along to the saddle above the mess of trees. The main difficulty of the ledges is making sure you start in the right location. Once following the correct ledge, there are numerous rock cairns marking the turns you need to take so it is not too hard to stay on track. Once you get high enough, the route doubles back onto a much wider ledge with some trees and you simply need to traverse to the west back to the creek.

3. Upper Boy Scout Lake
The turn off at Upper Boy Scout Lake is not technically difficult but is important because it is where you will be leaving the Lone Pine Creek Trail and continuing on the Mountaineer's Route proper. The normal route involves turning off and heading south up a fairly loose slope to the next higher plateau. Most people prefer to follow the creek for as long as possible before turning up the slope. There are numerous cut-offs that traverse the loose slope, but these involve significant bush whacking and some deep sand so they are not as popular. At this point, if you need water you can instead continue on up to Upper Boy Scout Lake itself for water (be sure to filter and treat the water!) before continuing on. Rather than backtracking, you can take a cutoff across the slope to save time, but this involves a loose slope, so proceed with caution. This second option is outlined in red.

4. The Notch
The Notch is by far the most physically challenging portion of the entire climb, despite its unimposing sounding name. This portion of the climb involves ascending nearly 2000 ft. in a narrow, rock or snow filled gully up the north east face of the mountain. Depending on the time of year it is attempted, conditions can range from packed snow to endless loose rock and gravel. When the gully is filled with snow, ice axe and crampons are required but the climbing is reasonably pleasant. In late summer when all the snow has melted, the climb is a much different animal requiring rock hopping and navigation of endless loose rock. Any late summer climber should be prepared for sliding back as much as climbing up; picking the correct line here is very important.  Due to the sudden altitude gain, this is often where climbers get hit hardest with altitude sickness. For the purposes of both climbs, I will need to ensure that I summit and start back down with plenty of daylight as The Notch is awful to descend in the dark. In all seasons, a rock helmet should be considered mandatory.

5. The Final 400
The Final 400 is imaginatively named as it is the Final 400 feet of climbing before you reach the summit plateau. In true mountaineering fashion, Mt. Whitney saves the best for last. The Final 400 is a Class 3 section requiring scrambling and some climbing to reach the summit. While it is the most technically difficult climbing of the route, it does not pose too big a challenge in the summer. In winter, this section is notoriously icy and dangerous, but summertime conditions allow for climbing without the need for ropes or gear. In fact, the most difficult portion of the Final 400 is the first 8 feet which requires you to climb up a an awkward rock shelf. After the initial shelf is cleared, you simply need to weave back and forth along the rock ledges to the summit. Below I have outlined one of the more common approaches, though there are endless variations. Once you reach the top of the Final 400, you are on the summit plateau a short distance from the summit hut.

So, what is the best way to train for climbing mountains?  The answer is quite simply, "by climbing mountains."  Unfortunately, most people (myself included) do not have the time or the easy access to large mountains to reliably train this way. What this means is that we have to come up with an approach to training that works all the same muscle groups and mimics the motions and strains you will be placing on your body.

To make sure I am properly prepared for climbing, I will be focusing my training in three main areas listed below:

Cardiac Fitness
Being in good cardiac shape is the most important area to be fit while climbing at high altitude. Not only do I need to worry about the physical difficulty of climbing the mountain, but I need to consider the effects of lower oxygen on my system. At sea level, there is roughly 20.9% oxygen by volume in the air I breathe, but as the altitude increases, the oxygen available decreases steadily. By the time I reach the summit of Mt. Whitney, there will only be 57% as much oxygen as there would be at sea level, meaning every breath will only have about 11.9% oxygen by volume in it. In short, this means I will need to take two breaths to get the same amount of oxygen I would in a single breath while training at sea level. Because of this, I need to be in great shape to allow me to function well with a heavily increased heart rate.

Leg and Core Strength
While working on leg and core strength might seem like a no-brainer to some, I often find that people don't always fully understand just how to go about training these muscles for mountaineering. For most people, when they think increasing leg strength they will naturally think of running paired with leg presses in the gym. However, both of these workout routines aren't well suited to making you a strong mountaineer. While running is a good way to build cardiac strength, it won't offer much help while climbing a mountain. Running strengthens muscle groups best used to propel you over flat ground with your weight directly above your hips, but while climbing steep mountain slopes, you will be hard pressed to find this motion being required. As for leg presses, they build large, fast twitch type muscles that are great for lifting up a large weight a few times. Unfortunately, mountaineering doesn't require you to lift a heavy set of weights a few reps then rest; it requires you to do it hundreds and hundreds of times in a row. To best prepare myself, I plan to leave both training methods out of my training plan and focus on the typical "stair stepping" motion which is what is most commonly found while mountaineering. This strengthens the muscles that are best for supporting me while my center of gravity is forward of my hips and my upper torso is leaning forward. This also strengthens my core which will allow me to balance and support a heavy pack load on uneven and steep slopes. I have found that hanging leg lifts paired with lunges and squats wearing a weighted pack are best for strengthening the muscles needed. Of course, there are many other ways to strengthen the correct muscle groups than I use. Remember our mantra when thinking of alternate training, "The best way to train for climbing mountains is by climbing mountains." Always tailor the training method to the end use.

    Training for endurance is by far the most straightforward of the three focuses to my training, but also the most difficult to do properly. The single day summit attempt I'm planning will involve at least 10 hours of continuous effort to complete. To best prepare for a long effort I will be using both long duration hikes and interval training on my bike to boost my overall endurance. I plan to use a bi-weekly fast hike of around 10 miles to condition my legs to long distances at a fast pace. Interval training is a technique where you alternate between high intensity workouts and resting. My goal with interval training is twofold: it will boost my recovery rate and increase my lactic threshold. Both of these factors together will allow me to recover from hard hiking faster and go longer without getting sore.

    In the previous installment of this series, The Road to Whitney 1: The Start of It All I laid out an initial training plan shown below:

    • Cycling: 4 to 5 days. 25+ miles per ride.
    • Hiking, non weighted pack: 1 day every other week. 5-10 miles.
    • Stair climbing, weighted pack (10-25 lbs): 3 times per week. 500 vertical ft. equivalent.
    • Squats, lunges, and wall sits: 3 times per week. 30 reps each.
    • Hang bar leg lifts: 4 times per week. 10-30 reps.
    This training regimen has so far been quite effective but as we begin to move into spring I plan to add additional workouts to build upon the athletic base I have built up so far this winter. My dad is (hopefully) following the training plan I created for him, which is quite similar. The new training plan looks something like this:

    • Cycling: 4 to 5 days. 25+ miles per ride.
    • Cycling intervals: 3 days. 10x 2 minute reps.
    • Hiking, weighted pack: 1 day every other week. 10 miles fast pace.
    • Stair climbing, weighted pack (30 lbs): 4 times per week. 800 vertical ft. equivalent.
    • Squats, lunges, and wall sits: 4 times per week. 30 reps each.
    • Hang bar leg lifts: 4 times per week. 10-30 reps.
    The final major obstacle to consider for this trip is training for the altitude.  While nothing compares to Mt. Everest, Mt. Whitney still tops out at 14,505 feet and poses a non trivial altitude challenge. The main obstacle to climbing at high altitude is the possibility of developing symptoms of altitude sickness or AMS (Acute Mountain Sickness). In the altitude range of Mt. Whitney, the most common symptoms of AMS include headache, dizziness, fatigue and nausea. As altitude increases into the range of Mt. Everest (20,000ft +), the initial symptoms grow in severity and you begin to accumulate fluid in the lungs and your brain swells.  Unfortunately, once symptoms develop there is very little that can be done to treat the effects other than descending to a lower altitude. For this reason, it is vitally important to acclimatize properly before climbing to high altitudes. Acclimatization is accomplished by slowly ascending to higher altitudes in increments of around 1000-2000 feet per day and then descending again. Doing this repeatedly allows the body to build up a reserve of red blood cells to better carry oxygen and allow your body to cope with the reduced oxygen at higher altitudes.

    Fortunately for me, my Whitney climbs only require that I contend with the more mild symptoms of AMS; but even these can be a trip killer as I live at an elevation of around 20ft. On a climb this past year, I ascended too quickly while climbing Mt. Tom Ross in the Sierras and I became fairly disoriented and developed quite a bad headache. All this led me to climb the wrong ridge on the approach to the summit and become temporarily lost; not something that is advisable in the wilderness. Fortunately, I have enough experience with the symptoms of AMS that I immediately aborted my summit attempt once I realized I was in the wrong place and my symptoms were getting worse.

    To ensure that I am properly acclimatized for both Whitney trips I plan to use a two part strategy to acclimatize. First,  I plan to climb another Eastern Sierra peak name Mt. Dana (13,061 ft.) in the weeks prior to my first trip. The great thing about Mt. Dana is that it is a very short climb (6 miles round trip) which will allow me to summit and get back down quickly. While I certainly won't be properly acclimatized, this climb will give my body a head start on the acclimatization for Whitney and allow me to gauge my overall fitness at altitude. The second phase will involve arriving at the Mt. Whitney portal campground (8,360ft.) and camping for two nights before I climb to the summit. After the first night, I will climb part way up the trail to around 10,000 feet and then descend again for the second night. This should allow my body to acclimatize enough to summit the following day with hopefully minimal altitude symptoms.

    While all this training should prepare me pretty well physically for climbing, every pound of gear I don't need to haul to the summit will make the going that much easier. So how do you pack light for a trip like this? My plan is to minimize weight where possible without going so far as to resort to an ultralight set up. Ultralight is a backpacking method where every ounce that can be shaved is done away with by using extremely light and minimalist gear. This lightweight approach is all well and good, but in mountaineering it is quite difficult to do away with some of the heavier items due to their essential nature when weather conditions go south.

    Over the years I have learned that the best way to control weight without resorting to extreme measures is to simply limit or reduce the amount of gear you can take. There is often a tendency to bring every piece of gear "just in case" and so you end up with a stuffed pack that weighs a ton. My favorite technique for limiting the amount of gear I take is by simply limiting the amount of pack space available. To help me do this, I keep a minimum gear list that always comes with me no matter the length of trip. I then create a second list of additional items I will need that is specific to the trip length and terrain I will be encountering. Below I have examples of both the minimum gear list as well as a list for both my single and multi day climbs of Mt. Whitney.

    Backpack comparison (2).jpg
    My trip packs

    Mountaineering Minimum Gear List
    • High top boots
    • Long pants
    • Wool socks
    • Thermal underlayer
    • Fleece or down jacket
    • Thermal hat
    • Waterproof gloves
    • Long sleeve shirt (or arm covering)
    • Brimmed hat
    • Sunglasses
    • Headlamp (w/ spare batteries)
    • Rock helmet
    • Leather rock gloves
    • Water filter and Iodine tabs
    • Sunscreen
    • Food (~300 cal/hr)
    • Water (.5L/hr)
    • Knife
    • Compass
    • Paracord (50ft.)
    • Trekking poles
    • Map
    • Backpack rain cover
    • First aid kit
    • Waterproof/windproof shell
    • Rain pants
    • Cameras
    • Aspirin

    Mt. Whitney Single Day Trip
    For my single day climb of the Mountaineer's Route, I will be using my Deuter Futura 32L pack (pictured left above). My biggest concern for a one day push is keeping the pack light. Every bit of weight I don't bring is that much less energy I will need to expend. However, I still need to balance staying light with the requirements for safely climbing the mountain. In addition to the minimum gear list, I will need the following items for the Mountaineer's Route:
    • Gaiters
    • Crampons (snowpack dependent)
    • Small tarp (if rain is expected)
    • Camelback bladder
    • Water treatment drops (due to polluted water)
    • Ice axe (snowpack dependent)
    • Whitney zone permit
    • WAG bags (required)
    Overnight Trip
    The overnight trip is going to be by far the more difficult of the two trips to pack light on. The addition of a sleeping bag, pad, and some shelter means there is simply more gear than on the single day climb. For this trip I will be using my other climbing pack, the REI Pinnacle 35 (pictured right above). While not much larger in terms of absolute internal volume (35L vs 32L), the Pinnacle has a more open internal layout that is better suited to holding bulkier gear like a sleeping bag and bear can. Since my dad is coming along on the overnight trip, we will have two packs to use for splitting gear that can be shared. In the list below, I note which items will be shared. This list is in addition to all the items from both lists above.
    • Small ground tarp (shared)
    • Sleeping pad
    • Stove fuel (shared)
    • Cup/bowl
    • Small bear canister (shared)
    • Sleeping bag
    • Ultralight stove (shared)
    • Cooking utensils
    • Rain shelter (if rain is expected)
    • Cooking pot (shared)
    Now, you probably noticed we are not bringing a tent. We are doing this primarily to save weight and because sleeping out under the stars in the Sierras is a great experience. Of course, this assumes the weather will be good. In case of bad weather, we will probably lug along a lightweight shelter but I am hoping this is not required.
