Black Diamond M Coefficient LT Quarter Zip Pullover

A lightweight performance fleece for mountain athletes who move hard enough to push through static midlayers, the Men's Coefficient LT Quarter Zip Pullover from Black Diamond runs 119gsm Polartec Power Grid fleece in a 92% recycled polyester/8% elastane blend. The Power Grid architecture creates a gridded interior surface that increases surface area for moisture transport, wicking perspiration faster than flat-knit fleece of comparable weight. The quarter-zip chest opening allows heat dumping on the move without a full layering stop, and the athletic-fit cut reduces bulk under a shell without binding through the shoulders. At 119gsm, the Coefficient LT Quarter Zip Pullover is the lightweight-active tier of the Coefficient line, built to sit between a base layer and a waterproof shell on aerobic mountain days rather than replace a heavier fleece for static use.
