My horse, Sugar, LOVES both her visor and her fly mask. The visor easily fits over her bridle and she is so much more comfortable riding on a sunny day. Sugar is very sensitive to light. Before these products, she was squinting a lot. My vet told me about both the visor and fly mask and, since using them, I have a different horse. She used to look for any bit of shade she could find and now, with her fly mask on, she stands out in the arena in full sun. I highly recommend both of these products.
