The Rab Xenair Vest is an essential layer for high-out alpine adventures, offering ultralight, breathable, and packable insulation. Designed with wind-resistant Pertex Quantum Air material that shields us from fierce winds on exposed climbs and a highly breathable lining that keeps us cool the harder we work. The body-mapped insulation provides warmth and comfort in chilly weather, plus it isn't too bulky, so we can layer over it in chilly weather. The semi-elasticated armholes ensure comfort during intense activities, while the three zippered pockets provide practical storage.
