Put on the Rab Women's Traverse Zip Off Pant for your next day on the trail, and adapt to the sun as it arches overhead and heats up the mountain. In the cool morning, the DWR finish and quick-drying nylon guards your ankles as you trek through the dewy underbrush. When you warm up on the inclines, there's no need to uncomfortably roll up these pants; just unzip the legs and continue up the windy path in shorts. The gusseted crotch lets you stretch over boulders without busting seams, and the UPF 35 nylon prevents sunburn on your thighs and calves on the brightest days.
