The Black Diamond Men's Alpine Start Hooded Jacket keeps wind and light rain at arm's length whether you're on the approach or arete. Weighing a mere 8. 5 ounces and featuring a stowable design, this jacket fits great in your pack or attached to your harness, and it won't weigh your alpine rack down too much. Climbing specific gussets allow your arms full mobility, while the helmet compatible hood keeps your head protected from the elements. Schoeller softshell fabric is highly breathable, so you can hike fast and climb hard, and the jacket is treated with Nanosphere technology, making the stretch fabric resistant to both moisture and dirt.
