This lightweight, stretchy Lycra fly mask is made out of patented "Coolcore" material that offers the ultimate combination of wicking, moisture transportation and regulated evaporation. The chemical-free, 100% washable, material works to move sweat away from the body while accelerating drying and providing a consistent cooling effect. This equine fly mask features binding around the edges for a perfect fit and fine mesh around the eyes and ears that ensures protection from flying insects while maintaining visibility.
