If your horse is particularly bothered by flies, this may be the mask to try. The fine mesh shaped veil and fleece trims keep even the smallest flies and midges at bay. The addition of a fly fringe that moves with the horse helps deter flies from the muzzle area. Elasticated at the poll for improved fit. Specially designed from breathable fabrics for all day comfort with adjustable touch close safety straps. UV protection - the mesh over the eyes (and nose) provides 60+% UV protection, helping to diminish the risk of sun burn and sun bleaching.
