Stash Collapsible Water Bottle

When you're bikepacking through the wilderness, every ounce of weight and inch of space counts. Some gear doesn't have room for compromising when it comes to space — spare tubes, socks, and tools can't be skipped, and while water is the lifeblood of your ride, you can downsize your hydration with the Hydrapak Stash Collapisble Water Bottle. Unlike traditional water bottles that continue to take up space in your bags when empty, the Stash spins down and collapses into 1/4 the size it is full, maximizing your space until the next watering hole.

The Stash weighs in at only 3.3-oz, a fraction of the weight of most standard water bottles, and can be used to host both hot or cold drinks, so you can leave your titanium mug at home, and use this multi-purpose bottle for your morning java before you start riding. It's made from a durable TPU that holds up to use and abuse on the trail and despite its light weight, its welded seams can take abuse from the elements. Even when empty, it easily holds its shape open, making it completely compatible with backcountry water filters to keep your hydration clean.
