The Kuhl Men's Edge Polo Shirt features an innovative fiber treatment that keeps you cool through the hottest rounds of golf and sunniest hikes. To achieve a Crystal Polish finish, the organic cotton receives a very light brushing with an ultra fine brush. The fabric becomes super soft but not peached. Peaching occurs when brush strokes sand the upper fibers to soften the endpoints. Crystal polishing sands the fibers to such a fine degree that the ends are not only polished, but they also become shorter. With shorter fiber lengths on the outer surfaces of the cotton, less air is trapped and the fabric holds less heat. Wildfibre Organic Cotton with crystal polish finishing is not only softer against the skin it's truly Kuhl!
