Soundproof bonnet with the longest ears?

Trying to avoid having to get a custom made bonnet. I am borrowing a Schockomohle soundproof one from a friend, but the ears are too short for my moose of a mare.

Does anyone know of a brand that has soundproof ear bonnets with 8.5” or longer ears? Preferably a brand I can find here in Canada, but if I have to order it in I will! Most websites don’t list the dimensions, so I’m at a bit of a loss.

Do you have a bonnet that currently fits your moose? I have soundproofed my OG bonnets with some neoprene from the fabric store. It worked out a lot better than I had expected!

I’ll measure both of mine for you tomorrow. I have a horse size Equifit that does fit my mare with pretty large ears well (they make oversize too). Also have an Eskadron - I find that one is easy for her to shake off and maybe a smidge too short in the ears.

This Etsy seller is making me a soundproof bonnet. She will make it according to my measurements, so I’m sure she’d do the same for you. Just be sure you measure correctly. Prices are very reasonable compared to some I’ve seen online that are $49+++
