Description

The lightest Gamma Pant available, this hiking pant uses a highly breathable, recycled double-weave fabric that sheds light rain and wind to help you comfortably push through unexpected weather, steep climbs, and hard miles. A slimmer fit and articulated patterning offer a clean look with plenty of space to move naturally — on and off the trail.

Updated with FC0 material for a lower Footprint USA, an improved buckle system, and design lines that align with the Gamma Collection.
