Derby Originals premium UV-Blocker fly masks feature a mix of traditional design and premium features to give your horse the most comfortable fit possible while ensuring total protection from biting insects. These fly masks are made from sturdy mesh materials that are non-heat-transferring and breathable, while also blocking up to 75% of all UV rays. Our innovative lycra fly mask is perfect for horses who remove, toss, or damage traditional fly masks. The snug-fitting lycra body of this fly mask is much harder to remove or pull off than traditional velcro closing fly masks, and the soft mesh bug-eye bubbles design prevents eye irritation. If you want to ensure your horse's safety and comfort against pests like flies, mosquitoes, and gnats this summer, look no further than our world-class fly masks. Our bug-eye fly mask is unique in that it features reflective material around the eyes and ears to promote visibility and safety!
