This ball cap just doesn't just keep the sun off—the Heatgear® sweatband also wicks away sweat to help keep your head cool and dry. The breathable, textured-knit fabric is super-soft for all-day comfort and an ultra-soft feel. A larger back opening allows for multiple ways of wearing your hair. UA Free Fit: Pre-curved visor and unstructured front conforms to your head for a sleek, low-profile fit.
