What Our Gearhead(R) Experts Are Saying:"I've used the Odin 1 World Infinity Jacket on long, mixed-weather days, and the balance of breathability and protection really stood out. The ventilation zips make it easy to regulate heat without slowing down."High routes often mean unpredictable skies, and the Odin 1 World Infinity Jacket helps us stay ready for whatever moves across the range. The waterproof and breathable Lifa Infinity(TM) membrane offers dependable protection during exposed traverses, while the lightweight, three-layer construction keeps bulk to a minimum when we're climbing, scrambling, or transitioning through ridge terrain. The hood adjusts easily and fits securely over a helmet, letting us move between sheltered and steep sections without interrupting our rhythm. Designed with input from mountain professionals, the jacket includes mechanical ventilation zips for fast heat release, stash pockets that stay accessible with a pack on, and articulated sleeves for efficient mobility on technical approaches. A built-in Recco(R) reflector and an emergency whistle add situational readiness when conditions deteriorate or visibility drops. From early-morning ascents to wind-packed ridgelines, the Odin 1 World Infinity Jacket supports long hours in challenging mountain environments.
