Durable and versatile, the Catalyst Field Shirt brings technical performance and modern design to an adventure staple.

Drawing from the rich heritage of shooting jackets and heavy flannel shirts, Catalyst sets the standard for comfort and adaptability. Combined with a baselayer, Catalyst wards off the chill on summer nights around the campfire, or on early morning starts. Toss on a shell or jacket, and Catalyst provides breathable warmth without overheating.
