The SuperMask II has a double latch closure system which helps keep the mask on your horse. The double-latch closure is located under the jaw, making it difficult for other horses to reach and pull off. The soft fleece edging keeps the mask comfortable all day long while the see through mesh doesn't obstruct your horses vision. This soft, fleeced lined mask is perfect for protecting your horses eyes from flies and it is also a good defense against dirt, debris and harmful UV rays. | Farnam SuperMask II Horse Fly Mask in Green | Size XL
