Warm and breathable for high-intensity ascents. Tested by athletes as part of our Eiger Nordwand range, this jacket offers versatile protection as a mid- or outer layer. Quick-drying Polartec® Alpha® Direct Polypropylene insulation provides warmth in harsh conditions while allowing sweat to escape. The 20D Pertex® Quantum Air outer fabric combines breathability with elasticity for freedom of movement during rock and ice verticals. With a durable design and easy-repair features – like a fixable YKK® front zipper slider and a patch kit for on-the-go repairs – the Eiger Nordwand IN Flex Air Hooded Jacket is an efficient, versatile choice for alpine adventures.

I have worn it while snowshoeing in 20 degrees F with a wool t-shirt to using it with no shirt in 50 degrees F. It is exceptionally warm for the minimal bulk it has. Alpha Direct is amazing. I like that the pockets can be used as vents to help dissipate heat. I like the rugged zipper versus a thin zipper that s
