My husband prefers to wear gaiter style masks to protect himself from dust, bugs and debri while working outdoors or while riding his bike, ATVs and while boating. He puts one around his neck every morning before going out so that he will have it when needed. He wears glasses and this style does not fog up his lens like other types of masks do. On hot days, he likes to wet it with cold water, wring it out and wear it over his head, neck or face to help keep him cooler. During the colder months, it helps to protect him from the chilling winds. He really likes the design of this mask with the vintage style black and grey American flag graphic. This mask is lightweight and breathable.
