My last pair held up for 8+ years of ski touring and ice climbing. Just christened my new pair guiding a Vail to Aspen hut trip. Sun, rain, and snow...we had it all and I was comfortable throughout. Broke trail through big snow (3/7/19) from Diamond J to Margy's. Perhaps some of the deepest snow Central Colorado has seen. So happy with the pocket selection, a place for everything! Durable and functional. They work 7 days a week.
