Having worked together previously, Reigning Champ and HAVEN join forces in the creation of a new line of shirts exclusive to the Canadian retailer. Known for their fleece offerings, Reigning Champ has had a great deal of production know-how thanks to its affiliated brand Wings + Horns. The Raglan Button Down Shirts feature a construction suitable for comfort and mobility together with triple stitch reinforcements and underarm eyelets for breathability.
