Our 90% UV protection masks for horses and ponies with sensitive eyes

Our recovery masks for horses and ponies returning from the clinic

Why choose an Equidiva flexible mask to protect your horse's eyes?

Features of Equidiva fabric
After four years of experience (customer feedback and veterinary opinions), we know that our UV-protective eye masks for horses are the most effective on the market. As you can see in the photo above, the fabric used is micro-perforated (each hole measures 0.5mm x 0.5mm), combining optimal opacity and transparency, which is necessary to ensure the horse's safety when moving around. It is also water-repellent and protects against wind and dust.

Comparison with a traditional canvas

These two photos show the difference between the traditional fabric used for masks that you find in tack shops or online, and the fabric used forEquidiva horse masks. The photo above shows the fabric used to make traditional masks, with holes measuring between 1.5 mm and 2 mm. This difference in perforation explains the effectiveness of our products. Before making a purchase, check the UV protection rating indicated.


What size should I choose for my Equidiva mask/hat?

All measurements are approximate and are provided for informational purposes only.

Size guide - Premium or Helios mask

Using a tape measure (or a piece of string that you will measure afterwards), measure around your horse's head as shown in the photo:


Mask size Head circumference
XS - Shetland* 84 cm
S - Poney* 90 cm
M - Cob* 94 cm
L - Full* 100 cm
XL - XFull* 110 cm
If your horse's head measurement falls between two sizes, we recommend choosing the larger of the two.



Size guide - Equivizor masks (Lightweight, Arso, Convalescence models)

For these masks, the main measurement is the width of your horse's forehead. To do this, you need to add together three measurements:

  1. Start at the outer corner of one eye and measure upwards at a slight angle to the middle of the forehead (measurement A).
  2. continue along the front of your horse(measurement B),
  3. Finish the measurement by directing the line slightly downward to the outer corner of the other eye (measurement C). This way, you will measure the widest part of your horse's forehead.

Add these 3 measurements (A+B+C) to obtain the size of your horse's forehead.

IMPORTANT: Do not measure directly from one eye to the other, as this will likely result in an inaccurate measurement.
