The Mammut Eiger Free Pro HS Hooded Jacket cuts its fit from a climbing-specific pattern, so it moves with the body through narrow couloirs and tricky, technical lines instead of just riding along for the descent. The 3-layer GORE-TEX PRO shell carries a confirmed 28,000mm water column and a breathability rating under 13 m^2Pa/W, holding up to deep powder and sustained climbs without trapping heat. A RECCO(R) reflector adds a layer of searchability if a rescue situation ever comes up. What Our Gearhead(R) Experts Are Saying:"I climbed a narrow couloir with a harness and pack on, and the articulated fit never once bound up at the shoulders or hips the way a standard ski jacket does. The shell shrugged off spindrift and brush the whole way up and never let moisture through on the sweatier sections."
