Hydrapak says:
When you’re going for your personal best, running out of water is not an option. Essential equipment for every adventurer, the 1 liter Stash is large enough to handle all-day hydration, expanding for use and crushing back down for maximum pack space. Compact, flexible and 50% lighter than a hard bottle. It’s construction with purpose.
Hydrapak's Stash Collapsible Water Bottles are an ideal hydration system for those who don't have a lot of storage space when their on the move. It folds down flat so it can be easily stored in your pocket and takes just seconds to pop open, ready to fill.
The material feels like a 'soft flask' but with a plastic bottom and top so it's a little more sturdier. Each bottle has a detachable loop so it can be easily hung on the outside of your pack.
