Mammut’s alpine tech has yet to let us down, so we trust their Aenergy WB Hooded Wind Jacket to defend us from chilly alpine air. The Pertex Equilibrium shell features a unique double-weave design with a tightly-woven, wind-blocking exterior and a looser, moisture-wicking interior, allowing high activity without perspiration compromising the day’s adventure. Stretch panels at the arms keep us mobile while climbing, and a helmet-compatible hood provides coverage without sacrificing safety.
