Poly/Spandex Blend Performance Material This fabric combination makes the cap lightweight, highly breathable, and slightly stretchy. This ensures a comfortable, secure fit even during prolonged wear or physical activity, making it ideal for sports and outdoor adventures. Sweat Stain Resistant Engineered with advanced technology, this cap is designed to repel sweat and its salts, preventing them from easily soaking into the fabric. This means the cap will maintain its fresh, new appearance for much longer, resisting those common white or yellow stains, even after heavy use in hot weather. Snapback The back features a classic adjustable plastic closure. This snapback design allows you to easily customize the tightness to fit various head sizes, making it a versatile, one-size-fits-most accessory. Slightly Curved Bill The cap's brim is not completely flat nor heavily bent. This subtly curved design provides a modern, stylish look while also offering just the right amount of shade and sun protection for your eyes.
