Black Diamond Men's Coefficient Fleece Jacket

Performance Fleece, No Compromises – Black Diamond's Coefficient Fleece Jacket in Alpine Blue

The Black Diamond Men's Coefficient Fleece Jacket is a technical midlayer built for athletes who demand performance from every piece of gear. Engineered with Black Diamond's precision construction, the Coefficient delivers exceptional warmth-to-weight performance in a streamlined fit that moves with you on the approach, the route, and the ridge. The alpine blue colorway is clean, confident, and versatile — sharp on the mountain and refined enough for post-adventure wear. When the temperature drops and the terrain gets serious, the Coefficient is the fleece serious athletes reach for.
