Prana Switchback Long Short The Switchback Long Short from Prana offers a little more coverage on the thighs, to protect from sun, scratches, and who knows what else. It’s made from a stretchy, quick-dry nylon, so not only is it perfect for a climb or hike, but afterward you can jump right into that mountain stream and cool off. The Switchback features an elastic waist, articulated knee, built-in gusset, and even a climbing brush holder. And it looks good, too, with contrast stitching and clean styling.
