Horseware Rambo Plus Mask with detachable ear and nose cover

This renowned fly mask has proven its effectiveness against flying insects, as well as its comfort and durability. We recommend it for horses that have recovered from illness and have no eye conditions, or as a complement to an ophthalmic mask. UV protection: 60%.

Lightweight and completely flexible, it can be worn continuously throughout the summer to protect your horse's eyes, ears, and nose from flies and horseflies.

Specific features of the mask:

- The Horseware Rambo Plus mask is preformed at the eyes thanks to a hoop that keeps the fabric away from the eyes and prevents rubbing.

- Featuring soft polyester around the ears and fleece lining, the Rambo Plus mask effectively protects your horse while providing comfort.

- The Rambo Plus mask is equipped with a removable nose guard attached with Velcro to protect the horse's nose from the sun and flies.

- The ear fabric is stretchy and loose to maintain freedom of movement for the ears.

- The stretch Velcro closure also provides maximum comfort when the horse is grazing and, more generally, an excellent fit.

Highly resistant fabric ensuring a flawless mask and good durability.

Wash with cold soapy water and a brush or in a washing machine on a cold cycle, short program, low spin, ideally protected in a laundry net.

Color: silver and navy blue

Tailles :XS (grand poney A) – S (poney B et C) – M (cob/petit cheval) – L (cheval)

Please note that this product runs large! If you are unsure, choose a size smaller than your usual size.

Equidiva Premium Mask with 90% UV protection and ear covers

This unique ophthalmic cap is the perfect complement to ophthalmic protection/goggles for horses. It provides excellent insulation and is therefore recommended for mid-seasons or winter. For summer, opt for the Hélios mask, which is lighter and more breathable, yet just as effective. Completely flexible, the Premium mask can be worn permanently and safely by any horse requiring special eye protection (uveitis, ulcer, cataract, etc.), both in the field and in the stall. It also provides effective protection against wind, dust, hay stalks, rain, etc.It can be used for outdoor work or flatwork. Given its opacity, we do not recommend using it for jumping; for these disciplines, opt for Evysor goggles orequigoogs.

Designed in two parts combining two technical materials, it will ensure maximum comfort and protection for your horse:
- Cap section: water-repellent stretch fabric. Closes with a wide Velcro strip and one adjustable strap under the throat.
- Eye section: durable, micro-perforated coated fabric providing optimal protection from UV rays, wind, dust, hay, etc.

- 1 removable inner foam pad keeps the fabric away from the horse's eyes.

- Semi-rigid headgear provides excellent support for the mask and ensures that the fabric remains away from the eyes.

Wash with cold soapy water and a brush or in a washing machine on a cold cycle, short program, low spin, ideally protected in a laundry net.

Tailles :XS (shetland) – S (poney) – M (cob) – L (full) – XL (XFull)

Please note:

If you have taken out insurance covering your horse's veterinary expenses, the purchase of eye protection required in the event of an accident or the treatment of an ophthalmic condition may be covered in whole or in part by your insurance company. If this is the case, and subject to its terms and conditions and the policy taken out, it will require the products to be prescribed by your veterinarian on the prescription they give you.

Horses are not designed to wear masks! Make sure at least once a day that the mask has not moved and that your horse is comfortable wearing it. We take the utmost care in manufacturing our products and selecting materials, but every horse is different and it is your responsibility to check that the equipment you have chosen (model + size) provides the necessary protection for your horse's eyes.

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.
