The Flexfit delta is a revolutionary cap that is the lighter, sleeker, smarter and more comfortable choice. It fuses panels with a seamless, stitch-free finish and it couples a lightweight visor fabrication with a new 3-layer multifunction sweatband. There is even patent-pending stain block technology that prevents sweat staining on the cap's crown. On the back there is a high quality hook and loop closure for stepless size regulation.
