When alpine conditions turn serious and temperatures plummet, the Patagonia R1 Thermal Full-Zip Hoody delivers the perfect balance of warmth, mobility, and technical performance for mountaineering and technical climbing. Built from stretchy Technostretch fleece with an innovative microgrid backing, this alpine climbing hoody traps essential warmth without the bulk while moving seamlessly through every crampon placement and mantling move. The low-profile hood fits flawlessly under climbing helmets, eliminating dangerous gaps and bunching that can compromise safety during technical ascents. With its smooth outer face shedding wind and light snow, plus thoughtful details like zippered chest pockets and discreet thumb holes, this recycled polyester fleece becomes an indispensable mid-layer for serious mountaineers who refuse to compromise between warmth and performance when the mountains demand their best.
