CHARLES OWEN Ayr8 Ventilated Riding Helmet Size: 56-57 Made in England, so the helmet shape is oval. I matched the width, and there was a little space in the front and back, so I used sponges to make it fit. The suede is rough in places, but I think it's still usable. I only used it for competitions, so the logo and the metal fittings on the back are rusty. I have never fallen off a horse while wearing it. Ventilated design with mesh material and black suede. Adjustable strap.
