Five best fly masks for horses in 2026: Tested for UV protection and durability

When fly season arrives, finding the right protection for your horse becomes a priority. Flies aren't just annoying. They can cause stress, spread disease, and create behavioral issues. But there's another threat that often gets overlooked: UV radiation.

Just like humans need sunglasses, horses with sensitive eyes, pink skin, or pale coats need UV protection. The sun's rays can worsen conditions like equine recurrent uveitis, cause painful sunburn on pink noses, and accelerate eye damage in older horses.

At Kensington Protective Products, we've been shielding horses since 1954. We understand that choosing a fly mask means balancing protection, comfort, durability, and the all-important "stays on" factor. This guide compares the five best fly masks for horses in 2026, tested across these criteria.

What to look for in a fly mask

Before diving into specific recommendations, let's break down what separates a good fly mask from a great one.

UV protection percentage matters more than most riders realize. A standard fly mask might block 60% of UV rays, which works fine for the average horse. But horses with uveitis, pale eyes, pink skin, or a white blaze need 90% or higher. Think of it like sunscreen: SPF 30 versus SPF 50 makes a real difference for sensitive skin.

Material type affects both protection and comfort:

• Textilene® mesh (1000 x 2000 Denier) offers the best durability and UV blocking. It's what we use in our UViator line, manufactured in Alabama.

• Fine mesh keeps out smaller insects but may lack the structural integrity for rough horses.

• Lycra/Spandex provides a secure, second-skin fit but offers less protection against biting insects.

• Mosquito mesh (350D) has a tight weave that stops even tiny midges.

Fit and sizing determine whether the mask stays on. Features like forelock holes prevent rubbing, while double darts keep mesh away from the eyes. The closure system matters too: double Velcro fasteners are harder for horses to undo than single straps.

The "stays on" factor might be the most important consideration of all. A mask that ends up in the dirt every morning isn't protecting anything. Design elements like the three-hole cap (ears plus forelock) or stretch fleece polls can make the difference between a mask that stays put and one that becomes a pasture decoration.

The five best fly masks compared

Here's how our top picks stack up against each other:

Now let's look at each mask in detail.

Detailed reviews of the five best fly masks

1. Kensington UViator CatchMask

Best for: Overall durability and maximum UV protection

The UViator CatchMask represents over 70 years of refinement in equine eye protection. We've designed it for horses that need serious sun defense (those with uveitis, pink skin, pale eyes, or any condition where UV exposure causes problems).

The 90% UV blocking comes from our Solar Screen Textilene® fabric, a 1000 x 2000 Denier material manufactured in Alabama. This isn't marketing speak. Textilene® is specifically engineered to withstand fading, fire, mildew, and the kind of abuse horses dish out in pasture. The 78% air permeability means your horse stays cool while staying protected.

What sets the CatchMask apart is right in the name. The double-locking throat closure includes a loop that lets you clip a lead rope directly to the mask, effectively turning it into a halter. For horses that need 24/7 protection, this means no more switching gear for turnout, feeding, or moving between pastures.

Key features:

• 90% UV protection with 78% air permeability

• Soft fleece-lined interior prevents rubbing

• Forelock opening protects mane from breakage

• USA-made Textilene® construction

• Lifetime Guarantee

Pricing:

What owners say:

The premium price reflects the premium materials and our lifetime guarantee. For horses with medical needs, this is the investment that pays off in reduced vet bills and improved quality of life.

2. Cashel Crusader Fly Mask

Best for: Horses that lose their masks

If you've ever walked into the pasture to find your horse's mask lying in the dirt (again), the Cashel Crusader deserves your attention. Its signature feature is a patented three-hole cap design: two holes for the ears, one for the forelock. This creates a remarkably secure fit that stays in place through rolling, rubbing, and general horse antics.

The Crusader uses a soft, coated nylon micro-mesh rated at 70% UV protection. That's not quite medical-grade, but it's a solid step up from basic masks and sufficient for horses without specific sun sensitivity issues.

Cashel offers multiple configurations: standard, long nose (for pink-nosed horses), and versions with or without ear coverage. The long nose with ears typically runs $39.99, while the standard model sits around $36.99.

Key features:

• Patented three-hole cap for secure fit

• 70% UV protection

• Soft coated nylon micro-mesh

• Multiple coverage options

The trade-off: While the Crusader excels at staying on, the 70% UV rating may not be sufficient for horses with uveitis or serious sun sensitivity. For those cases, you'll want to step up to the 90% protection category.

Horse owners consistently praise the Crusader's retention. One forum user noted it's the "most secure fit of any mask I've tried." For the Houdini horse that seems to remove every mask you try, this is your starting point.

3. Rambo Plus Flymask by Horseware

Best for: Horses sensitive about eye contact

Some horses simply cannot tolerate anything near their eyes. They spook at shadows, rub constantly, or toss their heads when wearing standard masks. For these sensitive souls, the Rambo Plus offers a solution: a reinforced band that runs across the forehead, creating rigid structure that keeps the mesh far away from the eyes.

Horseware calls this the "structured eye guard," and it's the primary reason riders choose the Rambo Plus. The textilene construction provides 65% UV protection, which is lower than some competitors but sufficient for horses without medical conditions.

The mask includes soft polyester ears, fleece edging for comfort, and a detachable nose piece you can add or remove as needed. It typically retails for $59.95.

Key features:

• Reinforced band creates maximum eye clearance

• Structured design prevents collapse

• Detachable nose piece

• Soft fleece edging

What owners say:

The structured design does make the mask feel bulkier than soft-mesh alternatives. Some horses need a few days to adjust to the sensation. But for horses that panic when mesh touches their eyelashes, that rigid structure is exactly what they need.

4. SmartPak UV90+ Fly Mask

Best for: Highest UV rating available

If UV protection is your absolute top priority, the SmartPak UV90+ delivers the highest rating on the market: 98% UV blocking with UPF 50+ certification. This is the mask for horses with photosensitivity, skin cancer history, or any condition where every percentage point of UV protection matters.

The mask uses a fine, soft mesh with UV protection woven directly into the fabric. According to SmartPak, this means the protection won't wash out over time, a claim worth noting if you frequently clean your horse's gear.

The softer material is gentler on sensitive horses than rigid constructions, but this comes with a trade-off in durability. The UV90+ is best suited for horses that aren't rough on their equipment. Turned out with playful pasture mates or prone to rubbing on fences? You might find the softer mesh shows wear faster than heavy-duty alternatives.

Key features:

• 98% UV protection (highest available)

• UPF 50+ rating

• UV protection woven in (won't wash out)

• Soft, comfortable mesh

Pricing:

For horses with medical needs requiring maximum UV blocking, the UV90+ is a strong contender. Just be realistic about your horse's temperament and how rough they are on gear.

5. WeatherBeeta ComFiTec Deluxe Fine Mesh

Best for: Budget-conscious buyers wanting quality

Not every horse needs premium protection, and not every budget allows for it. The WeatherBeeta ComFiTec Deluxe offers a solid middle ground: quality construction at an accessible price point, typically $26.99 to $29.99 depending on configuration.

The fine mesh construction blocks 60% or more of UV rays while maintaining excellent visibility. Double darts keep the mask shaped and away from the eyes, and the stretch fleece poll creates a secure fit that most horses find comfortable.

WeatherBeeta offers extensive sizing (Mini through Warmblood) and multiple color combinations, making it easy to find a match for your horse's build and your aesthetic preferences.

Key features:

• 60%+ UV protection

• Fine mesh for good visibility

• Extensive size range (Mini to Warmblood)

• Multiple color options

• Budget-friendly pricing

The trade-offs: The 60% UV rating is entry-level. It's fine for the average horse during fly season but insufficient for medical conditions. The darts, while helping with fit, can collapse over time with heavy use.

Horse & Hound gave this mask their "Best overall fly mask" designation with a 9/10 rating, citing the "really fine" mesh and secure fit. For the price, it's hard to beat.

Fly mask materials explained

Understanding what your mask is made from helps you choose the right protection for your situation.

Textilene® (1000 x 2000 Denier) represents the premium tier. This USA-made fabric blocks 90% of UV rays while maintaining breathability. It's the same material used in patio furniture, engineered to withstand sun, mildew, and abrasion. The trade-off is price: Textilene® masks cost more upfront, though the durability often makes them cheaper over time.

Fine mesh (various deniers) is the standard for most fly masks. It offers good visibility and keeps out flies, but UV protection varies widely. Check the specific rating before buying.

Mosquito mesh (350D) uses a tighter weave specifically designed to stop tiny insects. If you battle no-see-ums or gnats more than horse flies, this is your material.

Lycra/Spandex creates that second-skin fit some horses prefer. It stays on remarkably well, but the stretchy material offers less protection against actual bites. Think of it as a comfort-focused option for horses that tolerate flies but need sun protection.

Tips for keeping fly masks on

Even the best mask can't protect a horse if it's lying in the pasture. Here's what experienced owners have learned:

Measure before buying. A mask that's too large will slide and rub. One that's too small creates pressure points that horses work to relieve. Take the time to measure your horse's face according to manufacturer guidelines.

Double Velcro beats single. Masks with double-locking closures are simply harder for horses to remove. Look for this feature if your horse is a "Houdini."

Consider the halter-over-mask strategy. For chronic mask removers, some owners put a breakaway halter on top of the mask. The halter prevents the horse from pushing the mask off, and the breakaway feature maintains safety.

Try no-ear designs for pasture buddy problems. If your horse's mask keeps coming off and you suspect their pasture mates are "helping," an earless design removes the handles other horses grab.

Check fit regularly. Horses' faces change with condition, season, and age. A mask that fit perfectly in spring might need adjustment by fall.

Invest in your horse's comfort and protection

Choosing the right fly mask means balancing your horse's specific needs against your budget. A horse with uveitis needs the 90%+ UV protection that medical-grade masks provide. The average trail horse might do fine with 60-70% protection and a secure fit.

At Kensington, we believe in "Shielding What Matters Most." That means different things for different horses. Our UViator line was designed for the horses that need maximum protection: the ones with pink skin, pale eyes, and medical conditions where every percentage of UV blocking matters.

Our Textilene® fabric, double-locking CatchMask® design, and lifetime guarantee reflect our commitment to those horses and their owners. As we like to say: "If you need sunglasses, your horse needs them too."

Frequently Asked Questions

How long should a horse wear a fly mask each day?

Most horses can wear fly masks throughout the day during fly season. Horses with medical conditions like uveitis may need 24/7 protection. Remove masks periodically to check for rubs and let the face air out.

Should horses wear fly masks at night?

Unless your horse has a medical condition requiring constant UV protection, nighttime masking usually isn't necessary. Night masks should be removed to prevent moisture buildup and allow the face to rest.

What size fly mask does my horse need?

Measure from the center of the horse's forehead to the tip of the nose, and around the widest part of the jaw. Most manufacturers provide sizing charts. When in doubt, size up rather than down.

How do I clean a fly mask?

Most fly masks can be hosed off or washed in cool water with mild soap. Avoid harsh detergents that might degrade UV coatings. Always check manufacturer instructions, as some materials require special care.

When should I replace my horse's fly mask?

Replace masks when you see significant wear: holes in the mesh, frayed seams, or Velcro that no longer holds securely. For horses with medical conditions, replace more frequently to ensure UV protection hasn't degraded.

Do fly masks really help with UV protection?

Yes, quality fly masks with stated UV ratings provide measurable protection. A 90% UV blocking mask significantly reduces sun exposure for sensitive horses. Look for specific percentage claims rather than generic 'UV protection' labels.

Why does my horse keep removing their fly mask?

Horses remove masks due to poor fit, discomfort, or simply because they can. Try a more secure closure system, check for rubbing, consider an earless design if pasture mates are pulling it off, or try the halter-over-mask strategy for chronic removers.
