We've used, Cashel, Kensington, Wrangler, Schneider's, Pro's Choice, and probably some that I've forgotten about.
Ears, long nose and lots of UV protection.
I'm starting to think I'm going to have to use a sheet, neck rug and attach all 3 things together to keep the mask on. Skippy is the worst for slipping them off and/or just plain destroying them that I've ever seen. He's fine with his fly sheet but the MASK!!!!! And that's what he needs the very most to protect his pretty blue eyes and pink nose.
Any suggestions for a Horse proof fly mask?
