The Flexi-Fit visor allows your head to breath, keeping you fresh and dry during a race. Lightweight and comfortable, it keeps the heat off so you can concentrate on improving your time. Let nothing get in your way. The sweat band prevents sweat from getting in your eyes, while the visor protects your forehead from UVA rays. The adjustable band lets you adapt the visor as you like, to prevent it from moving while you run.
