The Black Diamond Coefficient LT Quarter Zip is a performance midlayer built for high-output activities. Featuring Polartec® Power Grid® fleece with a gridded interior for increased wicking performance and added breathability, the center-front quarter zip allows you to dump heat on the go, while the hoodless-style makes this an easy layer with other hooded jackets.
Patented grid construction knit strengthens performance efficiency by increasing warmth and breathability, while also reducing fabric mass. These geometric patterns improve compressibility, wicking, and add technical style. By reinventing thermal warmth possibilities, Power Grid™ is a minimalist design that maximizes fabric performance.
