The Mountain Hardwear Kor Preshell is a shockingly lightweight wind-layer designed by and for climbers and mountain athletes. It moves like butter and is fairly breathable when you're working hard, so it's easy to forget when you're wearing it. The Kor Preshell has three pockets, with one designed for stuffing into when you need to stash this puppy on your harness. What this thin softshell offers in terms of being ultra-light, ultra-packable, and fairly wind-resistant, it lacks in terms of durability, water resistance, and overall protection from the elements. That said, if you need an ultra-light wind layer for fair-weather climbing days or mountain running, the Kor Preshell is one of the best options around. Condition Like New Armpit-20” Length-25”/26”
