The LTM6C AIRFLO® Tilley Hat is a fusion of broad brim styling and a lightweight neck protector. To battle sun, wind and rain, the neck protector unrolls discreetly from the rear brim to shade all angles of the neck. Designed with a 3/4" polyester mesh built into the crown, this lightweight Hat offers superb ventilation and is made from Tilley Nylamtium®, a strong water-and-mildew resistant form of nylon.
