Indigo Super Gauze M-shirtThe M shirt, with its dropped shoulders forming the shape of an M, has a relaxed width and an always comfortable silhouette. Over the years, our Supima organic super gauze has continued to evolve. It offers the coolness of breathability, the warmth of fabric that holds air, and a smooth, refined luster. Often called the cashmere of cotton, it is a testament to Japanese craftsmanship and the thoughtful spirit of 45R.
