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. Guaranteed to last through one fly season.
