When you’re carrying everything on your back, having multi-function, multi-purpose gear makes the most sense. The Bitterroot Dry Bag for instance. This thing will keep your gear dry with its roll-top closure & watertight construction. With a couple lightweight accessories, it will filter your drinking/cooking water—it’s constructed of a NSF-approved potable water material & can also be used to inflate your air mattress & other inflatables.
