Charlie Bugg-Off Shield Fly Mask Without a doubt, the very best flymask on the market today. Made of soft yet very durable mesh that allows for nearly unobstructed vision. We have placed stays into the seams over the face to assure that the material will remain up off the eyes. We have placed soft fleece with a low nap as trim for additional comfort, but it will collect little dust or shavings. Sizes: Large Horse, Horse, Cob/Pony
