Fitting and Care Tips:
1. When putting the mask on your horse, approach the horse from the left side. Directly approaching your horse with the mask could startle him.
2. Open the two locking fasteners and place the ears through the mask with the forelock over the trim and mesh. Secure both the locking fasteners under the jaw.
3. Once the mask has been fastened with the right amount of snugness, check each side of the horses face by allowing your fingers to slip comfortably between the mask and your horse. The mask fabric should not be too close to your horse’s eyes; ensure the eye lashes do not poke through the material.
4. Straps can be adjusted for a custom fit. Checking the mask daily is recommended. Examine the condition of your horses face and eyes. Check for any damage to the mask. Replace the mask if damage is found, as it is difficult to repair. It’s important to keep the mask clean. Wash the mask periodically, with mild soap and water. Caution: vision may be impaired during rainstorms.

Ok to leave on at night?
Karen S on Feb 16, 2018
BEST ANSWER: I don't because my horses can shelter in a barn at night when the flies aren't bad. It's like a halter--if the mask gets hung up on something you aren't awake/aware to prevent an accident. I did have to cut this mask off my mare when she got a front hoof hung up by the border's edge around the jaw (it's very strong and didn't break but the mesh part somehow got torn). She is different about her front feet so she doesn't wear this brand anymore. IF the flies were horrible with no other alternative, I might leave this mask on a horse that's normal and less likely to rub up on something during the night.
