Recognized as the proven cure for helmet hair and the favored solution for lost travel combs and brushes, the Nike Dri-FIT FeatherLite Hat features a wicking Dri-FIT fabric made from polyester backed with an internal Dri-FIT double knit terry cloth sweatband. Unlike some cheap baseball caps or knit headwear, the Nike Dri-FIT FeatherLite Hat is optimized for comfort during workouts and travel. Nike added four mesh vents along the top seams to help enhance airflow while running, jogging and hiking. The underbill on the Nike Dri-FIT FeatherLite Hat is intentionally black to help reduce surface glare and water reflections--a feature that will appeal to anglers, kayakers and fly-fishing enthusiasts. Along the back of this cap is a Velcro-tab quick-adjust feature that easily adapts to a range of head sizes.
