Built-in moisture-wicking technology in the men's bottoms moves perspiration away from the body to provide a dry fit that's comfortable for all day wear

For greater flexibility and comfort, these men's bottoms for golfing feature a hidden elastic waistband that expands and contracts to move with you

Machine washable, these men's bottoms maintain their smoothness and good looks wear after wear, even with regular washing

Sun protection built right into the fabric prevents damaging UV rays from penetrating the material of the golf shirt to help protect covered skin
