The new standard for protection and comfort, our horse fly mask design keeps horses cool, dry and comfortable using high-tech fabrics originally developed for human performance clothing. It's designed to stay put with two way controlled stretch fabric on the crown and jowl, extended fabric behind the ears and a strong double locking hook and loop closure featuring wider Velcro. It's also designed to protect, with structured eye darts and a mesh that blocks 80% of UV rays. Plus, rolled inner seams prevent rubs and irritation. Assured to last through one fly season. Horse size without ear coverage and size with removable nose canister.
