Patagonia's Rock Guides are made of a lightweight stretch-woven nylon fabric blend that's tough enough to withstand the sharp crystalline scrambling of Joshua Tree. They provide 40-UPF protection from the harsh desert sun, and their Deluge® DWR (durable water repellent) finish also covers you in the event of an unpredictable torrent of rain. Articulated knees and a gusseted crotch allow effortless high-stepping and stemming. The athletic cut - now more streamlined with contemporary styling - includes forward-angled side seams and straight legs that easily roll up and stay in place through footwork-intensive routes. The button waist has a zip fly, belt loops and a brushed interior for next-to-skin comfort. Well-thought-out pocketing includes two front drop-ins, one zippered on the right thigh and two zippered below the back yoke. Inseam (size 8) is 32".
