The KUHL EDGE features Wildfibre Organic Cotton with a Crystal Polish finish for highly breathable and super absorbent comfort next to your skin. Wildfibre Organic Cotton is among the finest available cotton KUHL can source, and a comparable fabric is not readily found on the market. To achieve a Crystal Polish finish, cotton receives a very light brushing with an ultra-fine brush. The fabric becomes super soft but not as 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 length 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 - itÆ’‚‚Å¡‚‚Å¾‚s truly KUHL!
