The UV Ray Protection Sun Hat.

This sun hat provides a UV protection factor rating of 50--the highest UV protection standard in Australia where skin cancer rates are the highest in the world. It is made of tightly woven 100% nylon with a 7 1/2" neck flap that also protects the ears, and a 4" brim that protects the face. The lightweight hat has side mesh panels that vent moisture and heat, an external sizing band, and a Coolmax sweatband in the front of the rim. The hat can be easily cleaned with cold water and soap, and air-dried. Please specify Cream or Sand. Sizes M (21-22 3/4) or L (22 3/4-24). Made in the U.S. (3 oz.)
