Black Diamond Men's Alpenglow Long Sleeve Crew-TUNDRA

The Black Diamond Men's Alpenglow Long Sleeve Crew in Tundra is a performance long sleeve shirt engineered for climbers, hikers, and outdoor athletes who spend long hours under intense sun exposure. From desert multi-pitch routes to high-alpine approaches and scorching crag sessions, this crew delivers the coverage and comfort you need without sacrificing mobility or breathability.

At the core of its performance is UPF 40+ sun protection combined with BD.cool mineral-based in-fiber cooling technology. This advanced fabric reflects 71% of near-infrared rays, reducing perceived temperature while you wear it.

On hot days when the sun is relentless, that difference is felt immediately, keeping your core temperature more manageable so you can focus on the climb ahead. The Alpenglow Crew also features Polygiene odor control technology, an embedded fabric treatment using silver-chloride to inhibit the growth of odor-causing bacteria.

The result is a shirt you can wear more and wash less, suited for multi-day trips where laundry access is limited. The technical fit is designed to move with your body, providing a streamlined silhouette that layers well under a harness or shell without bunching or restricting your range of motion.

The Tundra colorway offers a versatile, understated tone that transitions naturally between the crag and everyday wear. Whether you are racking up for a long desert route or cooling down after a summit push, the Alpenglow Crew is the long sleeve shirt that earns its place in your rotation.
