Made from advanced fabric, our performance dress shirts are a sophisticated addition to the business wardrobe. We are using fabric that absorbs, stores and releases heat for optimal thermal comfort. This technology gives the ability to continually regulate skin's micro climate. As the skin gets hot, the heat is absorbed, and as it cools, that heat is released. Our dress shirts will proactively manage heat while controlling the production of moisture (sweat) before it begins. Details include semi-spread collar, mother of pearl buttons and single cuffs. All Kuul Thread shirts are made in USA.
