Horse Fly Masks & Sheets

About this category

Horse Fly Protection Gear

Flies don't just annoy horses — they cause real stress, stomping, and irritation that adds up over a long summer. Valley Vet's Fly Masks, Collars & Leg Guards collection covers masks, boots, collars, and sheets built to keep horses comfortable through fly season, the same practical way our founding veterinarians have approached horse care since 1985.

Types of Horse Fly Protection

Fly masks shield the eyes and face, fly boots protect the legs from biting insects, fly collars offer targeted relief, and fly sheets cover the body for horses especially sensitive to bites. Choosing the right gear comes down to fit, mesh visibility, durability, and how the piece will actually be used.

A few standouts in the lineup:

  • Shoofly Horse Leggins keep flies off the legs during turnout, trail rides, or warmup, cutting down on stomping and swishing and giving horses a noticeably calmer demeanor.
  • The SuperMask II Classic without Ears offers double-latch closure for a secure fit, plastic-coated mesh with 73% UV protection, and clear vision with no restriction on airflow — durable enough to last several seasons.
  • The Cashel Quiet Ride Fly Mask uses soft, breathable nylon mesh that fastens securely over the bridle without affecting vision, with added micromesh sleeves to protect the ears. Built for riding, not turnout use.

Getting Fit and Fabric Right

A fly mask that's too loose rubs and irritates; one that's too tight restricts movement and vision. Mesh visibility matters just as much, since a mask that limits sight can make a horse anxious rather than calm. Durability and seasonal use round out the decision — turnout pieces need to withstand all-day wear, while riding-specific gear like the Cashel mask is built lighter for shorter use. Pair your fly gear with our grooming aids or browse top selling horse supplies for the rest of your fly-season checklist.

Frequently Asked Questions

Should horses wear fly masks all day? 

Many turnout-style masks, like the SuperMask II Classic, are built for extended daily wear, while lighter riding masks such as the Cashel Quiet Ride are intended for active use rather than all-day turnout.

How tight should a fly mask fit? 

A properly fitted fly mask should sit snugly enough to stay in place without rubbing, with double-latch closures like those on the SuperMask II helping keep horses from pulling it off.

Do fly boots help with stomping? 

Yes — fly boots like the Shoofly Leggins are specifically designed to reduce leg-biting insects, which means your horse doesn’t need to do so much stomping and swishing to fend off flies.
