The Flexfit Delta® cap is made with seamless construction to minimize stitching and with patent-pending stain-block technology to keep the hat sweat and stain free. The multi functional 3-layer sweatband efficiently absorbs sweat, then the revolutionary stain-block tech comes into effect by diffusing the sweat through the under visor and letting it evaporate, preventing unwanted sweat stains on the hat. And of course, it features the original Flexfit® technology for definitive comfort.
