We're adventurers and we're always on the go, so we need a bedroll that can keep up with us like Mountain Hardwear's Bishop Pass GORE-TEX Sleeping Bag does. Being built with a GORE-TEX Infinium Windstopper membrane gives it greater resistance to those places where the weather has a tendency to get wet and windy. And while the winds howl and the rain beats down on the tent, we know we'll stay cozy and sleeping right thanks to the fluffy 650-fill down and heat-trapping design.
