Iron Heart CPOs are one of our favorite "shacket" styles for their spot-on fit and excellent use of fabrics. The IHSH-381 CPO is made of a mid-weight 9oz military cotton surge that is textured and durable. This fabric has been woven with a thinner warp yarn and thicker, uneven weft to create a more heavily textured weave. Sulfur-dyed, this shirt will break in a fade to vintage over time. This CPO is slightly longer in the body and features two chest pockets, two hand warmer pockets, and is finished with snaps.
