We need water to survive. What we don't need are the bulky, backpack-real-estate-stealing bottles we usually carry said water in. Enter the Hydrapak Stash, a collapsible, soft-walled water bottle that folds up flat—so you can fill it up when you need it and stash it almost anywhere when you're done.
Unlike other space-saving water bottles, the BPA-free Hydrapak Stash doesn't sag and flop around. Instead, you can stand it up on most surfaces thanks to a sturdy plastic bottom and screw-cap top.
When the Stash is empty, the soft walls of the bottle twist and allow the top and bottom snap together to create a small, flat disk you can simply slip into your pocket until you're ready to fill it again. The Stash retails for $23 and is dishwasher safe, durable, and — bonus points — could probably double as a Frisbee if you're really bored at camp.
