The Kentucky Horsewear Fly Mask Slim Fit is specially made from Lycra to provide a perfect fit, optimal comfort, and protection for the horse. It is highly breathable and durable. The Slim Fit Fly Mask acts like a second skin to prevent flies from entering the mask and offers maximum comfort. The extra-strong mesh eye covers prevent eye irritation as they do not touch the horse’s eyes. If they are pushed inward by the horse’s movements, they pop back out automatically! The fly mask features a zipper, a press button, and an opening for the forelock.
