6 Fly Sheets For Horses In Humid Climates Old Timers Swear By

There’s a certain stillness to a humid summer afternoon when the air feels thick enough to chew. While we can retreat to the air conditioning, our horses are left to face the sweltering heat and the relentless insects that thrive in it. A good fly sheet is more than a luxury in these conditions; it’s a critical tool for keeping a horse comfortable, sane, and healthy.

Beating Humidity: What Makes a Good Fly Sheet

The biggest challenge in a humid climate isn’t just blocking flies, it’s doing so without creating a personal sauna for your horse. A fly sheet that traps moisture against the skin can lead to rain rot and other fungal issues, trading one problem for another. The material is everything.

Look for a sheet made from a mesh that allows for maximum air circulation. Some materials, like Textilene, are stiffer and hold their shape away from the body, creating an air buffer. Others are softer, draping closer to the skin. There’s a tradeoff here: the stiffer mesh often breathes better but can cause rubs on sensitive horses, while softer mesh is gentler but may lie flatter, trapping more heat.

Color also plays a crucial role. Light-colored sheets—white, silver, or light grey—are non-negotiable. They reflect sunlight and heat, whereas dark colors absorb it, defeating the purpose of the sheet. Finally, consider UV protection. A good sheet not only fends off bugs but also protects against sun bleaching on dark coats and sunburn on pink-skinned horses.

Kensington Protective Sheet: The Gold Standard

When you see a horse in that classic plaid pattern, you know the owner invested in quality. The Kensington Protective Sheet is made from Textilene, a PVC-coated mesh originally designed for outdoor furniture. This material is incredibly durable and resistant to fading, tearing, and mildew.

The stiffness of the Textilene is its greatest advantage in humidity. It doesn’t cling to the horse’s coat, even when sweaty, allowing air to flow freely underneath. This structure provides fantastic protection from biting insects while keeping the horse noticeably cooler. It also boasts a 73% UV protection rating, which is a major benefit for horses living out 24/7.

The main consideration with a Kensington is the initial investment, as they are priced at the higher end of the market. The stiff material can also be a poor fit for horses with very high withers or unique conformations, sometimes causing rubs until it breaks in. However, for a horse that is tough on its wardrobe, this sheet will often outlast several cheaper alternatives, making it a sound long-term choice.

Schneider’s Dura-Mesh: Tough and Breathable

Schneider’s has built a reputation for making tough, well-fitting horse clothing, and their Dura-Mesh fly sheet is a perfect example. It’s designed for the horse that lives in a group and enjoys a good session of mutual grooming or pasture shenanigans. The material is a heavy-duty, ripstop mesh that resists snags and tears exceptionally well.

What makes it great for humid areas is the balance it strikes. While tough, the mesh is still highly breathable, preventing that sticky, trapped-heat feeling. The fit is also a major selling point, with an adjustable front closure and deep shoulder gussets that allow for plenty of freedom of movement without binding or rubbing.

This sheet is a fantastic middle-of-the-road option. It offers more durability than the ultra-soft sheets but is often more forgiving in fit than the stiffest models. It’s a reliable workhorse for the average horse in a typical pasture environment.

Cashel Crusader: Soft Mesh for Sensitive Skin

For the thin-skinned Thoroughbred or the horse prone to rubs, the Cashel Crusader is often the answer. This sheet is made from a much softer, more pliable mesh that feels more like fabric than a screen. It drapes comfortably over the body and is less likely to irritate sensitive areas like the shoulders, withers, and hips.

The Crusader offers excellent coverage, often with a slightly longer drop to protect the belly. The material is lightweight and breathable, making it a comfortable choice for hot, sticky days. Many models also feature unique darts and gussets specifically designed to accommodate a horse’s natural movement and prevent chafing.

The primary tradeoff is durability. Softer material is inherently more susceptible to snags and tears. This isn’t the sheet for a playful gelding that lives with a pasture bully. But for an older, quieter horse or one kept in a less challenging environment, the comfort it provides is unmatched.

WeatherBeeta Essential Mesh: A Reliable Classic

WeatherBeeta is a name that comes up again and again for a reason: they make dependable, well-designed products that fit a wide variety of horses. The Essential Mesh sheet is their no-frills, get-the-job-done fly solution. It’s built with a soft, durable mesh that offers good airflow without being overly delicate.

This sheet is a true classic. It features traditional shoulder gussets, twin buckle front closures, and low cross surcingles—a design that has proven effective for decades. The UV protection is solid, and the overall construction is what you’d expect from a reputable brand. It’s a safe bet if you’re not sure where to start.

While it may not have the extreme durability of a Kensington or the specialized fit of an Amigo, its strength lies in its versatility and reliability. It’s a fantastic option for a hobby farm with several horses of different shapes and sizes, as it tends to provide a good, serviceable fit for most.

Amigo Bug Rug: Superior Fit and Air Circulation

Horseware, the company behind the Amigo and Rambo lines, is known for its innovative designs focused on equine anatomy. The Amigo Bug Rug is a standout for its exceptional fit and airflow, making it a top contender for humid climates. It’s made from an extremely lightweight, soft, and breathable knitted polyester.

The key features are in the design. The patented "Leg Arches" allow the sheet to wrap closer to the belly for more coverage without restricting the shoulder or stifle. The classic V-front closure removes pressure from the point of the shoulder, a common spot for rubs. This combination makes it an excellent choice for horses with big shoulders or those that are very active in the pasture.

The material is treated to be UV protective and is designed to be cool and comfortable. Like other soft mesh sheets, it won’t stand up to extreme pasture antics as well as a heavy-duty mesh. However, for preventing rubs and maximizing airflow on a hard-to-fit horse, the Amigo Bug Rug is hard to beat.

Tough-1 Contour Mesh: Affordable Full Coverage

Not every situation calls for a top-of-the-line sheet. For a young, growing horse that will need a new size next year, or for a horse that only needs a sheet during the worst of the fly season, an affordable option like the Tough-1 Contour Mesh makes a lot of sense.

This sheet often comes as a combo with an attached neck cover, providing excellent full-body protection at a fraction of the cost of premium brands. The mesh is lightweight and breathable, and the contoured fit is designed to follow the horse’s natural shape. It does the basic job of keeping flies off without breaking the bank.

The compromise here is in the longevity of the hardware and fabric. You can’t expect a budget sheet to last as many seasons as a premium one. The stitching may not be as robust, and the mesh may be more prone to tearing. But for its price point, it provides incredible value and effective protection when you need it.

Care and Longevity: Making Your Sheet Last

A fly sheet is an investment, and how you care for it directly impacts how many seasons you’ll get out of it. Caked-on mud and sweat can degrade the fabric and reduce breathability. Regular cleaning is essential.

When washing, use a mild soap designed for horse blankets or a gentle, non-detergent cleaner. Harsh detergents can strip the UV-protective coatings and damage the mesh fibers. Always use cold water and, if possible, wash it in a large, front-loading commercial machine to prevent damage from a central agitator.

The most important step is to always hang your sheet to air dry. Never put a fly sheet in a machine dryer. The high heat can shrink the material, melt the mesh fibers, and destroy the integrity of the straps and hardware. A few minutes spent on proper care can add years to the life of your sheet.

Ultimately, the best fly sheet is the one your horse will wear comfortably without turning into a sweaty mess. Consider your horse’s skin sensitivity, pasture mates, and your budget. Prioritizing a light color, a breathable mesh, and a proper fit will make all the difference when that summer humidity sets in.
