When we're heading into the wilderness for a week-long escape, we've got all the necessities packed in this high-volume backpack. It's designed with suspended mesh along the backpanel that adds breathability and resists odor buildup. The hip and shoulder straps rotate with our bodies, letting us move naturally up the trail. Multiple access points and external storage areas let us access and organize our gear with ease while we're on the trail or packing up our camp.
