Filson Men's Denim Jac-Shirt in Vintage Black

The Denim Jac-Shirt by Filson combines the straightforward, familiar cut of a classic work shirt with the reliable warmth of an insulated jacket. Built with a heavy-duty 15-oz. 100% cotton denim shell in Vintage Black, it provides wind-blocking structure and rugged durability long trusted for work across the American West.

The interior body is lined with plush high-pile polyester fleece to trap core warmth, while the sleeves feature smooth polyester lining packed with 60g insulation to minimize bulk and layer cleanly over base garments. Designed for active wear, it features side-seam slits at the hem for unrestricted mobility and dual button-flap chest pockets to keep everyday essentials secure.
