How do you get the best of everything' You mix all the best ingredients into one delicious mix, and the same can be said for jackets. Just ask the designers over at Black Diamond who combined all the best ingredients of all the midlayers out there into one high functioning jacket that will be the only jacket you'll need most days. Chances are good that you're going to encounter a little foul weather when you're playing in high mountains. And since most weather systems don't necessitate the waterproof protection of a shell, it's nice to wear a midlayer that will deal with a little wind and precip, so you don't have to rush to put a shell on at the first sign high winds and grey clouds. Designed to combine weather resistance, breathabilitty, and insulation, the Black Diamond Men's Deployment Hybrid Hooded Jacket is a well rounded midlayer that you can wear once snow starts to fall when you're on the up track and maintain the breathability needed to keep you cool when your heart rate is up.The sleeves, shoulders, and hood of the jacket are composed of a weather resistant Schoeller stretch woven material with NanoSphere technology to shield you from wind and light precipitation. The rest of the jacket is composed of a merino wool material to offer the breathability necessary to keep you moving at a good clip during the ascent. Inside the jacket is a light, 80g Primaloft Silver hi loft insulation for increased warmth and a breathable mesh lining below that to help manage moisture and promote breathability. The actual layout of the jacket consists of a low profile hood, two chest pockets, and stretch cuffs, so you wear it comfortably with your climbing helmet and harness on.
