A lightweight version of Black Diamond's Coefficient fleece in a quarter-zip style, the Coefficient LT Quarter Zip Pro 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.
