Super Gauze M-shirtThe M shirt, with its dropped shoulders forming the shape of an M, has a relaxed width and a reassuringly easy silhouette. Through years of refinement, our Supima organic super gauze has achieved a balance of breathability that lets air flow through, warmth that holds air within, and a smooth, elegant sheen. Known as the cashmere of cotton, it embodies the quiet beauty of Japanese craftsmanship and the enduring philosophy of 45R.
