For those days that you know it’s going to be a grind, but you still have to protect yourself from the elements, go for the Black Diamond Coefficient LT 1/4 Zip. A stretchier and lighter version of the popular Coefficient Fleece, this second layer incorporates insulation without sacrificing breathability. The Primaloft insulated front panel keeps your core warm while the gridded pattern of the Polartec Power Grid fleece wicks sweat and dumps excess heat. A slim cut design makes it easy to layer over and under this apparel gem.
