equidiva for horses and ponies

2-mask pack: Helios without ear covers + equigoogs glasses

Size Guide
Helios mask size
Glasses tint

A Helios mask with 90% UV protection and a removable nose cover to protect your horse when resting.

The Helios mask protects against harmful sun rays, wind, hay, and of course insects. It is extremely comfortable thanks to the thick fleece that lines all areas in contact with the horse's skin. Its semi-rigid frame keeps the fabric away from the eyes, and the fabric of the hood allows air to circulate, which is essential during the summer months. It is also available in a version with ear flaps. It has a double closure system, with Velcro and buckles. As horses' eyes are on the sides of their heads, the noseband area does not enter their field of vision. The black band along the noseband has no impact on their field of vision, which is mainly lateral and rearward.

The Helios mask is the perfect complement to veterinary treatment for horses suffering from ophthalmological conditions such as uveitis, ulcers, conjunctivitis, keratitis, cataracts, etc. Completely flexible, it can be worn permanently and safely by any horse, whether in the field or in the stall.

Its long removable neck cover prevents sunburn for horses with light-colored skin and also provides relief for some horses suffering from headshaking. 

Specific features of the Helios mask:

  • Airy fabric between the ears and above the eyes,
  • Hoop to keep the fabric away from the eyes,
  • 90% UV-protective micro-perforated fabric to protect the eyes and nose,
  • Velcro closure at the underbust + strap and safety buckle,
  • Fleece lining on all parts in contact with the horse's skin.

A pair of equigoogs goggles to protect your horse at work

Equigoogs are lightweight, adjustable, stable, and comfortable goggles for Shetland ponies, ponies, horses, and heavy horses with sensitive or fragile eyes, allowing them to be ridden and worked normally.

These protective eyewear were designed with the help of veterinarians specializing in equine ophthalmology. The tinted version is ideal for ponies and horses with photosensitive eyes: squinting on white arenas, headshaking, etc.

Equigoogs glasses offer:

  • transparent or tinted polycarbonate shells that are 100% UV-resistant and unbreakable,
  • anti-fog treatment on the inside of the shells, anti-scratch treatment on the outside,
  • ventilation to maintain a dry environment inside the hulls
  • a seal used in the medical industry for perfect adhesion and optimal comfort,
  • With a unique dual-material fastening system (elastic + leather), the glasses can be used on their own, over a bridle, or attached directly to the cheekpieces of the bridle.

Precautions for using equigoogs

  • Equigoogs are glasses designed specifically for working with horses.
  • Do not leave them on an unattended horse that could rub the shells against a wall, fence, its legs, etc.
  • To be installed just before the work session and removed immediately afterwards.
  • At the end of the session, store the equigoogs in their case or, if you leave them attached to the bridle, protect each shell.

Equigoog maintenance

  • Gently wipe the equigoog shells with a microfiber cloth (clean and dry).
  • For the fastening system: grease the leather fastenings and brush the elastic parts (soft brush).
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 - Pony 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.
