Buff Coolnet UV Ellipse Headband - Retaining its recycled character from fusion bonded fabrics, the new BUFF Headband has taken a step forward. It's still comfortable and breathable and fits your head even better thanks to the new ellipse design. Whatever activity you do under the sun, stay cool and protected. CoolNet UV technology wicks sweat and wards off skin irritation, aside from blocking dangerous sun exposure. Comfort and protection, all in.
