Unpredictable mountain weather calls for dependable warmth. We put more fill in the body, where you need it the most, and kept the arms slim for a fashionable, performance look.

Straight-up flannel only goes so far in a Wyoming winter, which is why our Buckhorn adds 100% recycled polyester Thermore® Ecodown® synthetic insulation. Lofted by location—with more fill in the body, less in the sleeves—the organic, brushed-cotton flannel rolls loose but packs tech warmth underneath. Worn over a tech tee, hoodie or even another flannel, it fires up outdoor-rated warmth during backyard bonfires, parking lot tailgates or campground jam sessions. Hidden chest pocket snaps lock in supplies while handwarmer pockets stow or stand-in for gloves.
