A lightweight version of their 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.
