While it seems so far away now, Eli did have some sinus procedures that left a hole in his face the size of a half dollar. He could go back to work before the hole healed completely. I had a high level of apprehension about this and wanted some degree of protection for his face while he worked under saddle. He wore a regular fly mask 24/7 for a while, but I wanted something less obtrusive for riding. I found the Cashel Quiet Ride Fly Mask and Eli wears it now for many of our rides, just as he did when he went back to work after the sinus procedures.
Although the intended purpose of this fly mask is obviously to deter pesky flying insects, I have found Eli seems especially to prefer wearing it on super sunny, super windy, or drizzly days (or nights), too. I jokingly call it his sensory deprivation fly mask, but really this is just one more essential piece of equipment for Eli to help him stay focused. We also tried the Cashel Nose Net, but he strongly objected to that. He occasionally may have head-shaking tendencies, but I don’t think he’s truly a head-shaker to where the behavior interferes with daily activities — he just objects to extremely bright light and I can relate. If I can do something to ease the discomfort sunlight, wind, or drizzle can cause Eli when I need him paying attention to me, I will do that thing. That thing is this fly mask.
I can most definitely recommend this fly mask for riding — it helps deter pests and for Eli it has some added benefits. He has two because I always want a clean one ready to use. Conveniently enough, Riding Warehouse carries them for a great price.
