    Hydration without the hassle.

    Keeping hydrated doesn't mean you have to sacrifice half of your pack space to water bottles, just snag the Hydrapak Stow 500ml Water Bottle and you'll be on the way to hydration town without the bulk. This completely collapsible water bottle stows up to 500-milliliters of life-giving goodness for your hike, and features a loop that makes for easy carrying. When it's empty you can easily roll it up, and the carry loop doubles as a strap for keeping the bottle rolled up tight and out of the way, so you can toss it in your back pocket or whatever spare space you can muster in your pack. Because its made of flexible, ultra-durable TPU it can be folded to fit in the strange shaped small pockets, while still standing up to the rigors of camping, backpacking, and general trail abuse. Plus, it weighs in 80% lighter than most hard water bottles, so once its empty you'll barely notice you have it with you at all.

    The Solution to Multi-Pitch Hydration

    • Familiarity: I've used it several times

    After multiple pitches on the wall wondering why I hadn't solved for my hydration problem I finally stumbled upon this little gem. 500ml of water mixed with a little Skratch gets me through quite a few hours on the rock. As you drink, the bottle shrinks in size eventually to the point where the carry loop wraps around the bottle.
    I keep mine on the back of my rack and have had no issues with durability. I foresee it also being a great addition to my snowboarding setup this winter.

    Cool Little Bottle -- Ultra Tough

    • Familiarity: I've used it several times

    I picked this up for a quick, cold drink of water for my winter days lapping the mountain skiing. Sometimes, all I need is a small hit from the water bucket to keep me going until I call it for the day., and finally I've got it. This is tough, very well made, perfect for my internal jacket pocket and not too bulky or heavy that it's a lopsided distraction. Drink from it, collapse it, stash it and go. Versatile for other times too.

The spill-proof nozzle allows for easy drinking, it’s lightweight, easy to pack and the bail handle makes for more comfortable carrying and attachment. Convenience meets performance.
