Black Diamond M Alpenglow Long Sleeve Crew

Sun exposure is a constant on long desert routes and in the alpine, and the Alpenglow Long Sleeve Crew is built to handle it. BD.cool mineral-based in-fiber cooling technology reflects 71% of near-infrared rays, reducing perceived temperature during marathon belays and sustained approaches in direct sun. UPF 40+ sun protection pairs with Polygiene odor control technology that inhibits odor-causing bacteria, keeping the shirt functional across multi-day objectives without the weight of a synthetic layer. The Alpenglow Crew belongs in any desert or alpine climbing kit where sun management and all-day comfort are non-negotiable.
