Which Shires fly mask does my horse need?
The right mask depends on how much of the face you want to cover and where your horse is most bothered. Ears-only masks suit horses that rub their forelock or dislike nose coverage; ears-and-nose masks add protection for pink noses and sensitive muzzles; earless masks give more room for large forelocks. Use the table below as a starting point, then check the fit on your own horse.
| Coverage | Best for | Example (in stock) | From |
|---|---|---|---|
| Ears & nose | Everyday all-round protection, pink or sensitive noses | Shires Fine Mesh Fly Mask with Ears & Nose | £15.64 |
| Ear hole (forelock out) | Horses with large forelocks or that dislike covered ears | Shires Fine Mesh Fly Mask With Ear Hole | £17.09 |
| Ears, wide vision | Sensitive eyes; maximum field of vision | Shires FlyGuard Pro Fine Mesh Fly Mask with Ears | £17.99 |
| Stretch fit | Close, snug fit that moves with the horse | Shires Stretch Fly Mask | £18.00 |

How do I measure and size a Shires fly mask?
Shires masks are sold in standard sizes such as pony, cob, full and extra-full. As a guide, measure from the middle of your horse's forehead down to just above the nostrils, and compare against the size options on each product. Because head shapes vary between horses of the same height, a mask that fits well should sit clear of the eyes without gaping at the jaw. If you are between sizes or fitting a sensitive or hard-to-fit horse, ask your saddler or a knowledgeable stockist before buying.
How does a fly mask help with UV protection?
Many Shires masks use UV-blocking mesh that helps reduce the amount of sunlight reaching the eyes and face, which can support horses prone to sunburn on pink noses or those with eye conditions made worse by bright light. A fly mask is one part of good summer management alongside shade, fly rugs and, where relevant, veterinary advice — it is not a substitute for treatment. If your horse has an eye problem or persistent sun sensitivity, speak to your vet about the best approach.
How do I look after a fly mask?
Check the mask daily for grass seeds, dried mud or damage, and make sure it is sitting clear of the eyes. Most fine-mesh masks can be rinsed or gently hand-washed and left to air-dry; avoid harsh detergents that can stiffen the mesh. Storing it clean and dry between uses helps the fabric and fastenings last longer through the season.
Frequently asked questions
How much do Shires fly masks cost?
At Just Horse Riders, Shires fly masks start from £15.64, with most everyday fine-mesh and Deluxe styles falling between roughly £15 and £27 depending on coverage, size and colour. Fly veils and clearance lines can be lower, while combo and turnout products sit higher.
Should I choose a fly mask with ears, or without?
Masks with ear coverage help keep flies out of the ears, which suits horses that shake their head or are prone to ear irritation. Earless or ear-hole designs give more room for a large forelock and can be a better fit for horses that dislike having their ears covered. If your horse rubs a mask off, trying the other style often helps.
Do Shires fly masks add nose and UV protection?
Several Shires masks include a nose flap that helps shield sensitive muzzles and pink noses, and many use UV-blocking mesh that helps reduce sunlight reaching the eyes and face. This can support horses prone to sunburn, but it is part of good summer management rather than a medical treatment — ask your vet if your horse has an eye or skin condition.
What sizes do Shires fly masks come in?
Shires masks are generally available in pony, cob, full and extra-full sizes, though the exact options vary by model. Measure from the middle of the forehead to just above the nostrils and compare with the sizes shown on each product. If you are between sizes, or fitting an unusually shaped head, check with your saddler before ordering.
Can I wear a fly mask turned out in the field all day?
Many riders use fly masks for daytime turnout in the fly season. Choose a durable design such as the Deluxe or Field Durable range, check the fit sits clear of the eyes, and inspect it at least once a day for debris, rubbing or damage. Remove it if it becomes wet through, torn or displaced.
