Ladies with long hair, this one's for you! Ever tried to wear a regular baseball cap with a ponytail or messy bun? It's always awkward, right? This cap is specially designed with a cool criss-cross opening at the back that lets your ponytail or high bun slide right through. No more squashed hair or an ill-fitting hat. It's made from a soft, breathable cotton-polyester blend that feels comfortable even on sensitive scalps and dries quickly if you sweat or get caught in a little rain. The back has an adjustable Velcro strap, so it fits most head sizes (about 22 to 23.2 inches, or sizes 7 to 7 3/8). The slot for your ponytail is about 3 inches by 0.5 inches. It's a one-size-fits-most, unisex style that looks great on everyone. Perfect for workouts, hiking, beach days, festivals, or just running errands when you want to keep the sun off your face but don't want to mess up your hair. Throw it on with your favorite casual outfit and go!
