Compressible convenience for long races.
The Nathan VaporShadow Hydration Vest has a women-specific design all the storage you need to survive difficult races like the Leadville Trail Marathon. Dual stabilization and load lifter systems utilize dual sternum straps and a waist-belt to compress the included two-liter bladder and the rest of your gear close to your body in order to provide a stable, no-bounce ride throughout the race. Wall mesh shoulder straps bring a lot of breathability to help keep your shoulders sweat-free in warmer weather, and the insulated reservoir pocket prevents your warm body from heating up your liquids. The 2-liter bladder features a locking bite valve for easy drinking that doesn't drench you with water like other valves can.
The VaporShadow has multiple zippered compartment and stretch mesh stash pockets to keep you well-organized on the trail. The hidden internal back pocket is perfect for ice packs to help keep you cool, and Nathan designed its front bottle pocket to fit its 22-ounce Tru-Flex bottle so you can store it or any smaller bottle without a problem. The pack also has a zippered pocket for smartphones, a pocket for pills like electrolytes to keep you moving, and clips for trekking poles in case you need them on the trail. The external shock cord at the rear keeps everything compressed throughout the race so the pack feels tight from the moment you start until you cross the finish line.

Perfect for trail running
- Familiarity: I've used it several times
I just got this pack and after only a few mid-distance runs I think I have a new favorite adventure buddy.
Use-- I got this pack for my long runs. I've used fuel belts before as well as hand-held bottles, but for my really long training runs (marathon and ultra training) I was running out of water and needing more carrying capacity.
This pack is incredible.
Fit-- I'm a girl. I have a chest. Not a huge one, but a consistently 34B chest. THIS THING FITS. I got the S/M size, and honestly would have been okay if the straps cinched down just a tad more, but as it is they tighten down plenty for me, just without room to go smaller. What I love most is that the lower strap on the chest hits right at the same place as my sports bra band. Not only does this make it comfier, it also means there is a topographic barrier to keep the darn thing from riding up. It stays in place amazingly. I tightened down the top chest strap, but honestly never felt it while running.
Good fit = NO CHAFING. My skin blisters if it even comes within 10 feet of my running shoes (not quite, but seriously, it's "sensitive" to the max). This thing was designed for comfort. I haven't been quite brave enough to try it at shirtless o-clock over just a sports bra, but over a very thin tech shirt I was pleasantly surprised at the level of comfort. Once the bladder started to get emptier I could hear sloshing, but I never felt any bounce or change in the fit of the pack.
Hydration system-- it's easy to access, easy to fill, easy to empty/clean (except for the nozzle itself, which is a consistent problem of every bladder I've used including various generations of camelbak and platypus), and stays put nicely while running. I LOVE the magnet on the tube feature, making it easy to sip while moving. Bonus points: the tube disconnects from the bladder itself with a self-sealing mechanism, so the bladder stays full even when the tube isn't attached. I haven't had the opportunity to take advantage of this yet but I imagine in a race it would be great to swap out an empty bladder for a full compatible one without having to disconnect the tubing from the pack.
Extras -- This pack was well thought-out. I think they added reflective material to every possible surface, and even a few impossible ones for good measure. I like this, my safety conscious mom likes this, and my safety conscious dad is a huge proponent of the built-in emergency whistle. While not as good for entertainment as a built-in kazoo might have been, it's nice knowing it's there if I need it. There are tons of pockets, all of which are easy to access as far as I have found. Snacks (gels, honeystinger waffles, shot bloks) fit great in the front pockets to fend off the mid-run hangries/ bonking. I haven't had any issue with elbow/ upper inner arm chafing from the pockets, but maybe with different form that could be an issue as the pockets do extend laterally. Probably depends on your proportions, arm swing, and pack fit. I'm not sure if the "cell phone pocket" is quite large enough to be compatible with my mini-laptop of a communication device, but I haven't tried to say it doesn't.
Cosmetics: I love neon colors, so the purple/red/green scheme works great for me. If you're into being subtle or blending in, I'd pick a different color.
Bottom line: I am beyond impressed with this pack. I find it to be well worth the price tag, and look forward to many more chafe-free well-hydrated trail runs with it in the coming months.
Loving this for a bike pack!
Not too loose, not too tight....
Tighten up your pack if you're carrying a lighter load, or add some room for longer days with this fancy schmancy bungie.
Internal back pocket....
Add some ice to keep your core (and your water!) cool
so many pockets! the magnetic straw attachment is my favorite!
all the bells and whistles...
- Familiarity: I've used it several times
Literally you guys, this pack has a whistle.
This is the mother of all race vests. I usually like to run as minimally as possible--before this pack I always ran with a smaller, simpler race vest that could carry just enough water, a few snacks, and a light jacket. When I first slipped into this pack I thought it was just a little too much pack for me--it's big, lots of pockets, extra room.....WAIT...these are actually really awesome features! I love to run mountains, and sometimes I find myself out on the trail for hours and hours, or even the full day, and this pack is ideal for the runner who's out for longer-than-the-average run. (for shorter runs it really is a bit much)
Let's go over all the awesomeness from front to back:
-I've never worn a pack that that secures up so high--over my chest. My other packs/vests secure across my stomach. I wasn't sure how I'd like it, but it's absolutely fine. That being said, I'm a pretty flat chested gal.....I don't know how comfortable this would be for larger chested ladies. The straps across are long and there are lots of options for adjustments, but I just feel like if you're on the bustier side you might end up feeling a bit crammed in there.
-I LOVE the magnetic straw attachment.
-I love a small pill pocket for my salt tabs....although I do wish this was also magnetic (it's velcro)
-Right on the straps (which are wide, mesh, and super breathable) there is a drawstring pocket, a large zipper pocket, and a smaller elastic pocket (fits several gels).
-There is a detachable whistle that hangs off the front, just in case you encounter some kind of ferocious wildlife, fall off the mountain, or just get tired of the sound of your own breathing.
Two zipper size pockets between your front and back--great for more calories or a pair of gloves.
-The VaporShadow holds 2 liters of water, but also has enough pockets that I can stash my SteriPen in there if I need to.
-Right next to my back is a large stretchy pocket that runs the length of the pack to stash ice--keeping your core, and your water cool as well. I've never seen this feature and love the idea of it.
-Two large pockets that run the length of the pack--one zippered, one elastic. Great of snacks/extra shirt/socks/ t.p./you name it
-One more medium sized zipper pocket--more snacks! keys (I do wish this had one of those little key hooks in it)
-The pack also has an elastic cord zig-zaged across to tighten it up if your load is lighter, expand when you're carrying more, or when your water level starts to drop you can tighten the cord and redistribute the weight more evenly--how cool is that?
-Trekking pole clips if that is something you fancy
-Pretty flashy. I have to say I've never gotten compliments on a pack before--this one seems to bring out flattering comments wherever I go!
-Lots of reflective action going on if you find yourself on the streets in the dark.
FIT: I love the fit! This is a womens specific vest (men check out the VaporCloud)--it fits snug and against my body without rubbing or bouncing. I'm 5'4" 112lbs and wear the small.
This has been my first experience with a Nathan product and I was so happy to team up with them and Backcountry to review this great pack and share all of it's goodness with the Backcountry.com Community. And as long as we are talking about Nathan--please do yourself (and your friends) a favor and grab some of their Power Shower wipes.....nice for a quick "bath" after a day in the dirt--they truly make you feel more clean and I really dig the super fresh scent.
