Pull on the Stonepeak Flannel and roll from the bike path to the trail and everywhere in between in this sneakily tech, classic-looking shirt. We added a THERMOLITE® poly-cotton blend to our flannel to create a lightweight button-up that doesn't skimp on warmth. Made from 100% recycled textile waste, it offers temperature regulation for when your bike ride heats up on the hills. This regular-fit shirt comes with snap closures, a drop-in chest pocket, and a hidden zip-secure chest pocket, too.
