The Catalyst Flannel
Black Foundry ForgeWeave™ Performance Flannel
Built for hard work, open roads, and everything in between, the Black Foundry Flannel combines timeless plaid style with modern performance. Crafted from our signature ForgeWeave™ Performance Blend, it delivers dependable durability, lightweight comfort, and unrestricted movement without the heavy, bulky feel of traditional flannel.
The soft-touch performance fabric is breathable, quick-drying, and designed to resist shrinking, wrinkling, and fading while maintaining its shape wear after wear. Functional details—including dual snap chest pockets, adjustable cuffs, a center back box pleat, and hidden collar-stay buttons—make this flannel a reliable everyday essential.
Whether you’re on the job, around the campfire, or heading out for the weekend, it’s built to keep you comfortable and looking sharp season after season.
