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.

  • Carry loop doubles as a strap for securing it when collapsed

Can I put boiling water in this bottle?

Yes, although it will be very hot to hold. It isn't insulated so you will feel the heat.

Fill. Drink. Pack. Repeat. With durable construction and minimal design for easy packing, the flexible Stow 500ml helps make all your adventures the best they can be. Add the spill-proof nozzle for easy drinking, bail handle for comfortable carrying and attachment, and a weight 80% lighter than most hard bottles, and you’ve got a winner every time.

Awesome bottles!

    I love these for all activities. They're easy to throw in a backpack when going out for the day or on a hike, or in a crossbody bag when out for the evening, or in my trail running vest. Durable, easy to use and clean, I have multiple sizes and they're all awesome.

    Staying hydrated

    • Familiarity: I've used it several times

    Got this bottle to stash in my coat pocket while I'm skiing - both backcountry and resort. Have use it a few times and it has worked well for me. A little nervous about how durable it will be over time, but other reviews say it's held up well, so I'm optimistic!


      Great way to make sure you're not wasting any weight on your water container. It's soft material allows some more options for stowing and space maximisation

      Best water bottle ever!

      • Familiarity: I've put it through the wringer

      If you climb multipitch, you need this. They also fit in jacket pockets well when full, or you can chug down half and put it in your pants pocket.

      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.

      Perfect for Hikes & Camping!

        This water bottle is perfect for hiking as well as camping with friends. Extremely
        lightweight and durable.

        STOW Bottle

        A trail companion like no other, the flexible Stow 1L has an internal baffle that makes it easier to hold and pocket. 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.
