Cashel's Crusader Fly Masks are among the top-voted fly masks year after year and are trusted by horsemen of all backgrounds to protect their horses from flies. The Cashel Crusader Fly Mask is made from soft coated nylon micromesh, making it a very comfortable choice for fly protection for your horse. Its patented three-hole cap and double dart construction keep the material well away from sensitive eyes, lashes, and temples without damaging the forelock, providing a more natural and complete field of vision. The Crusader blocks up to 70 percent of the sun's damaging UV rays, protecting horses from eye problems and sunburn. This mask is great for horses that have greater sensitivity to the sun and lighter-skinned horses.
