Fly Sheet Basics

Fly Sheet Essentials: Keeping Your Horse Comfortable and Protected

Picture a warm, sunny day when tiny buzzing insects keep landing on you and the sun burns your skin. That is a bit like what spring and summer feel like for many horses. A fly sheet helps here. It is a lightweight, breathable coat that keeps your horse comfortable and shielded from the elements. This guide covers what you need to know before you buy one, and how to get the most out of it afterward.

Why Horses Need Fly Sheets: Far More Than Escaping the Buzz

A fly sheet does much more than keep flies off, and it earns its place in the tack room for several reasons. Think of it as a multi-tool for comfort and health in the warmer months.

Protection from Pesky Insects

Insect protection is the most obvious reason, and it matters a great deal. Flies, mosquitoes, gnats, and other biting insects do more than annoy a horse. Their bites itch and hurt, and in some cases they spread disease. A fly sheet builds a physical barrier that makes it much harder for these tiny invaders to reach the skin. It works like a personal force field against the bug army.

Shielding from the Sun (UV Protection)

Horses sunburn just as people do, especially those with lighter coats or pink skin. Strong sun can also fade a coat and turn a rich dark color into a duller shade. Many fly sheets include UV protection, which acts like sunscreen over the whole body. That keeps the skin safe and the coat looking its best. Healthy coats need support too, and you can explore products like those in our Coat & Body Care collection for that.

Preventing Skin Irritation and Allergies

Some horses react badly to insect bites. They get itchy bumps, rub the skin raw, or develop allergic reactions such as “sweet itch,” which causes intense itching and discomfort. A fly sheet cuts their exposure to those irritants a great deal and keeps the skin calmer and healthier. Horses with sensitive skin or existing irritations can benefit from specialized care products. Take a look at our Specialized Care & Protection products, or try the Repair Cream for soothing relief.

Keeping Horses Clean

Horses love to roll, and they come up dusty or muddy every time. A fly sheet works as a protective layer and keeps the coat cleaner for longer. You spend less time grooming, and the horse looks tidier. To keep manes and tails clean and healthy, explore our Mane & Tail Treatment products.

Types of Fly Sheets: A Style for Every Situation

Fly sheets come in several styles, much as we wear different outfits for different weather. The right one depends on your horse’s needs and on where they will wear it.

Standard Fly Sheets: These are the most common type, and they cover the main body from chest to tail. They give good general protection from flies and some sun.
Full-Coverage Fly Sheets: These go the extra mile. They often include an attached neck cover, a belly band to protect the underside, and a long tail flap. They suit horses that are very sensitive to bugs or need maximum sun protection.
UV-Protective Fly Sheets: Many sheets offer some UV protection, but these use materials that block a higher percentage of harmful rays. They are ideal for sun-sensitive horses and those with light-colored coats.
Waterproof Fly Sheets (Dual Purpose): Some clever designs have a waterproof top panel, so the horse stays dry in light summer showers and keeps fly protection too. That helps when the weather is unpredictable.
Riding Fly Sheets: Yes, you can buy fly sheets made for riding. They are usually cut to allow for the saddle and for rider comfort, so your horse stays bug-free on trail rides or schooling sessions.

Fly Sheet Materials: Light, Breezy, and Strong

The material decides how well a fly sheet works and how comfortable your horse feels. Most are made from special fabrics that are both durable and breathable.

Material Type	Description	Key Benefit
Polyester Mesh	This common fabric is lightweight and durable, with small holes.	It breathes well and works as a good insect barrier.
Nylon Blends	Manufacturers often mix nylon with polyester for added strength and smoothness.	The blend adds durability and resists tearing.
Special Weaves (e.g., Ripstop)	The fabric is woven to resist tearing and ripping.	It is very durable, and a small tear does not spread easily.
Silky Linings	Some sheets have a smooth lining on the chest and shoulders.	It prevents rubbing and keeps the coat smooth, which matters most around the shoulders where friction occurs.

The aim is a material light enough to keep your horse from overheating but strong enough to survive daily horse activity and keep bugs out. Good breathability lets air move through the fabric, which keeps your horse cool even on warm days.

Finding the Right Fit: Comfort Comes First

A fly sheet only works well if it fits correctly. A sheet that is too big tangles or rubs off, and one that is too small rubs uncomfortably and restricts movement. Here is how to get it right:

How to Measure Your Horse

Measuring a horse for a fly sheet is simple, and all you need is a soft measuring tape.

Stand your horse squarely on a flat surface.
Start the tape in the center of the chest, right where the sheet will close.
Run the tape along the side, over the widest part of the barrel (the tummy area).
Continue to the point of the rump where you want the sheet to end, usually just past the tail.
That measurement, in inches or centimeters, is your horse’s size. Most fly sheets come in increments of 3 inches (e.g., 72, 75, 78 inches).

Signs of a Good Fit

Snug but Not Tight: The sheet should lie smoothly against the body, with no gaping or pulling.
Shoulder Freedom: Your horse should move the front legs freely, and the sheet should not pull tightly across the chest or shoulders.
Adequate Length: The sheet should cover most of the body and usually ends a few inches below the point of the buttock, without hanging too far down.
Straps Adjusted: Leg straps and surcingles (belly straps) should be snug enough to hold the sheet in place and loose enough for comfort and movement. You should be able to fit a hand comfortably between the strap and your horse’s body.

Signs of a Bad Fit

Rubbing: Hair loss or sore spots, especially on the shoulders, chest, or withers, mean the sheet is probably too small or poorly designed.
Gaps: Large gaps around the neck or chest mean the sheet is too big, and bugs can get underneath.
Tripping Hazard: If the sheet hangs down past the hocks, your horse could step on it and trip.
Tightness: If the sheet pulls across the chest when your horse lowers their head to graze, it is too small.

Key Features to Look For: Details Make a Difference

Fly sheets come with a range of features that improve comfort, security, and effectiveness.

Front Closures: Most sheets have buckles or clips at the chest. Some use a single buckle, while others use two for extra security. A few offer a “V-front” or “quick clip” system that is easy to use.
Surcingles (Belly Straps): These straps run under your horse’s belly to keep the sheet from shifting. Criss-cross surcingles are common and spread tension evenly.
Leg Straps: These go around the hind legs, are usually detachable, and stop the sheet from blowing over in the wind. Adjust them comfortably and not too tight.
Shoulder Gussets: These extra folds of fabric at the shoulders give your horse more freedom when they walk, graze, or lie down, and they reduce rubbing.
Tail Flap: This piece of fabric extends over the tail and adds protection from flies to the sensitive tail area.
Neck Covers (Optional): Integrated or detachable, these protect the neck, which is a common target for biting insects.
Belly Bands (Optional): This wide, elastic band covers more of the belly for maximum protection, which helps horses sensitive to bites on their underside.

Caring for Your Fly Sheet: Keep It Clean and Lasting

A little care goes a long way toward making your fly sheet last and stay effective.

Regular Cleaning

Fly sheets get dirty quickly from dust, mud, and horse sweat, so clean yours every few weeks, or as needed.

Shake off loose dirt and hair.
Check the label for washing instructions, because most sheets can go in the machine on a gentle cycle with a mild detergent.
Avoid harsh detergents, fabric softeners, and bleach, since they can damage the fabric and reduce its breathability or UV protection.
Air dry the sheet completely to prevent mildew.

For the horse’s own baths, do not forget our Reluminate Shampoo or Revive Shampoo.

Storage Tips

Store your fly sheet in a clean, dry place when it is not in use, especially in the off-season. Fold it neatly or hang it up so it does not crease unnecessarily and so it lasts longer. Keep it away from rodents and other pests that might chew the fabric.

Checking for Damage

Inspect your fly sheet regularly for rips, tears, or broken straps. Small repairs are often easy and stop the damage from getting worse, which extends the life of the sheet. Prompt repairs also keep your horse fully protected.

When to Use a Fly Sheet: Timing Is Everything

Knowing when to put a fly sheet on makes a big difference to your horse’s comfort.

Summer Days: Summer is prime time. When flies are abundant and the sun is intense, a fly sheet is a daily essential for turnout.
Turnout: Whenever your horse is outside in a pasture or paddock during the warm months, a fly sheet offers continuous protection.
Sensitive Horses: Horses prone to allergies, sweet itch, or sunburn might need a fly sheet even on milder days or for longer periods.
After Grooming: After a bath with products like Reluxe Mane & Tail Shampoo or Repel Oil Shampoo, a fly sheet keeps your horse clean and protects the freshly conditioned coat. You might also apply a spray conditioner like Release Spray Conditioner for extra shine and protection before putting on the sheet.

Beyond Fly Sheets: Other Ways to Help Your Horse

Fly sheets are fantastic, but they are only one part of a complete horse care routine. Combine them with other strategies for the best defense.

Fly Sprays and Repellents: Use these on areas the fly sheet does not cover, like the legs or face, or when your horse is not wearing a sheet.
Mane & Tail Care: A healthy, strong mane and tail work as natural fly swatters. Keep them conditioned and tangle-free with products from our Mane & Tail Treatment category, such as Refresh Mane & Tail Cream, so they can do their job.
Specialized Skin Care: Horses with existing skin issues or sensitivities can get extra relief and protection from specialized products. Explore our Specialized Care & Protection range.
Shampoos: Regular bathing with suitable shampoos keeps your horse clean, and shampoos with natural insect-repelling ingredients can help deter insects too. Check out our various Coat & Body Care shampoos.
