What Is A Fly Mask and Why You Need One
Fly masks are an important part of your horse’s health. They protect the eyes from insects, pollen, and sunburn. They are just as important in winter as in summer!
Fly masks come in a variety of styles and sizes. It can be confusing to know which one to purchase.
This blog will walk you through buying a fly mask and the reasons your equine needs to be wearing one.
What Is A Fly Mask?
A fly mask is a head covering that fits over your horse’s face. The main purpose is to protect the eyes but they may also offer coverage for the ears and nostrils as well.
What Are Fly Masks Made Of?
The mask is made of a coated nylon mesh. There are different weights of mesh used. The sturdier mesh may be best for more active horses.
It is transparent and allows the horse to see and hear. Most horses adjust well to wearing them.
According to Riding Warehouse, there are 4 main types of material.
Airy, Ripstop Mesh - A light and breathable nylon often used for fly sheets but also masks. It has up to 65% UV protection.
2. Tight-Weave Polyester - Woven polyester, however, can tear easily so maybe not for the more active horse. 80% UV protection.
3. Textilene Mesh - This material is made of vinyl-coated polyester and is quite strong. 73% of UV rays.
4. Fine Window Screen Mesh - If you have gnats or "no-see-ums, this is the material for you. Fairly durable and provides up to 65% UV protection.

Features of Fly Masks
With Ears - some fly masks cover the ears. This is where knowing your horse pays off on getting the right mask. Some horses are a little touchy-feely when having their ears handled. Foundation training helps head shy horses.
Muzzle guard - Some masks have a flap that covers the nostrils and muzzle area. This is especially nice for light-colored horses with white or pink noses.
Eye Darts - some masks have stitched darts to keep the nylon fabric from rubbing against the horse’s eyes.
Make sure you have a good fit - see our guidelines below.

Finding a Good Fit
Fitting a mask can be tricky. It needs to be snug enough to stay on but loose enough to be comfortable.
The lower edge of the mask needs to come at least one inch below the bottom of the horse’s cheekbone. If it doesn’t it will cause a gap near the cheekbone that will allow easy flies to get in.
Make sure the mask does not rub against the eyes or it may cause a corneal ulcer.
Adjust the mask so it’s snug but not tight. You should be able to slip your finger easily between the horse’s face and the mask.
Many manufacturers provide a sizing chart. Kensington tells you where to measure and then you just plug your numbers in the chart.
How To Measure
Fly Mask Houdini
Is your horse a fly mask Houdini who takes off their fly mask as soon as you turn your back? I have one of those! My horse Rocket gleefully removes fly masks and leaves them down in the far field under a big pile of poo!
I realized this was a management problem and I needed to find a mask that fit him snugly and had strong velcro to hold it on.

How to Measure for a Fly Mask for a Horse
Materials Needed:
Measuring tape (preferably a soft flexible one)
Assistant (if possible)
Pen and paper (to note down measurements) or your phone
Step 1: Prepare Your Horse
Make sure your horse is calm and standing comfortably in a well-lit and safe area.
If possible, it's recommended to have an assistant to hold your horse steady during the measuring process.
Step 2: Measure the Forehead Width
Start by measuring the distance between your horse's poll (the highest point of the head, just behind the ears) and the outer corner of one eye.
Gently wrap the measuring tape around the forehead area and note down the width measurement.
Step 3: Measure the Cheeks
Measure the distance between the outer corner of one eye, following the curve of the cheek, to the corresponding outer corner of the other eye.
Allow for a snug, but not overly tight, fit. Ensure the measuring tape is in contact with the horse's skin throughout the measurement.
Step 4: Measure the Jaw Width
Measure the distance between the center of your horse's jawbone on one side to the center of the jawbone on the other side.
Make sure the tape is taut but not causing discomfort to the horse.
Step 5: Measure the Nose Length
Start from the center of the poll and measure down the midline of your horse's face to the bottom edge of the nostril.
Ensure the measuring tape is in contact with the skin but not pulled tight.
Step 6: Measure the Distance Between Ears
Measure the distance between the two ears at their base.
Make sure the tape is snug but not tight, allowing for comfortable movement of the ears.
Step 7: Check Your Measurements
Double-check all the measurements you've taken to ensure accuracy.
Compare the measurements to the manufacturer's size chart provided for the fly mask you intend to purchase.
In case your horse falls in between sizes, it's generally recommended to choose the larger size for a more comfortable fit.
Remember, accurate measurements are vital to ensure the fly mask fits well and provides the necessary protection for your horse. By following these step-by-step instructions, you'll be able to measure your horse correctly and choose the perfect-sized fly mask to keep pesky flies at bay.

When Should My Horse Be Wearing A Mask
“Always”, says Dr. Stephanie Bell of Hagyard Equine Medical Institute. "Fly masks are not just for summer and fly season. They protect your horse’s eyes all year long.
A horse needs to wear a fly mask all year long for several significant reasons. Firstly, fly masks act as a vital defense against pesky insects that constantly bother horses. Insects such as flies, gnats, and mosquitoes can cause significant irritation and discomfort to the horse's eyes and face, leading to potential infections or eye problems if left untreated.
Secondly, fly masks offer protection against harmful UV rays from the sun, making them an essential accessory even during the winter months when the horse isn't bothered by insects. UV rays can cause sunburn and skin damage, which can be prevented by wearing a fly mask.
Lastly, fly masks can also help reduce eye strain caused by bright sunlight, making it easier for horses to focus and perform their tasks with greater comfort and ease.
Fly masks should be worn all year long.
Tips From The Pros
Styles that have fleece padding across the poll and nose may be more comfortable, especially for a horse who likes to rub its head against things.
The UV masks promoted for summer are also great for areas with a lot of snow in the winter.
If you clip around your horse’s ears it may make them more prone to flying bugs. Consider a mask with ears.
If you buy a mask with ears make sure the ear coverings are big enough so your horse can turn and twitch their ears normally.
Remember a dirty mask is uncomfortable. Give the mask a good soaking in mild dish soap when it gets dirty. Then rinse thoroughly and line dry in a sunny spot.
