Black Diamond W Project Heavy Flannel

The Women's Project Heavy Flannel from Black Diamond is a burly brushed organic cotton button-up that earns its place in a crag kit through sheer durability and character. A boxy fit designed for layering over base layers and light midlayers gives it versatility from the campsite to the post-climb wind-down, and the heavyweight organic cotton construction provides more warmth and structure than the standard Project Flannel while still relying on no synthetics or pesticide-intensive farming. It only gets better with use.
