Mission Workshop might have just created the ultimate button-up for summer. The Hayes Button-Up is constructed from a material called 37.5, a high-tech fabric that keeps the body from producing liquid sweat and also traps odor molecules without using any chemical finishes and will never ever wash out. It also features a handful in  functional features like stretch, a side-entry breast pocket, pen pocket, and it's highly breathable to keep you cool this summer.
