HydraPak’s Stash Bottles (750ml & 1L) are versatile water bottles that should be in your pack if you’re trying to keep weight at a minimum and space at a maximum. These bottles are compact when not in use and flexible enough to withstand hard use. When packed up without water, these bottles twist down to a quarter of their expanded size, making them the ideal travelling and adventure companion. They can be frozen or filled with hot water. Low-profile handles around the lids make them easy to carry and clip-on to packs or carabiners. For your next day hike to Piute Pass or your next climb up Pine Creek, these bottles should be on your gear list!
