Black Diamond M Coefficient Hoody

A midlayer hoody for alpine climbers and ski tourers who need active-stretch insulation that breathes at sustained output without leaving a clammy feeling at rest stops, the Black Diamond Men's Coefficient Hoody is built with Polartec Power Dry High Efficiency fabric in a 51% polyester, 36% nylon, 13% elastane blend for four-way stretch and moisture management that outperforms a standard grid fleece at high heart rates. The engineered fabric moves moisture away from the skin and pushes it through the outer face without requiring a separate base layer in mild conditions. For alpinists who run warm on steep terrain but need warmth at cold belays, the Coefficient Hoody handles both ends of the exertion range without switching layers.
