I think Kraemer and a few other places here are starting to make bee keeper style masks with prices lower than Rambo. I wanted one but I'm not sure if it'd be tricky to get a halter on and off over one as my horse is brought to and from his field by staff at the yard.
The IDx mare hated her Rambo beekeeper fly mask with a vengeance, so I passed it on to the senior mare. Senior mare soon worked out that she could use it to aid her ‘head butting under the electric fence to get to the long grass‘ escapades.
It’s now hanging up in the tack room, unused.
