Your cart is empty. ONE K DEFENDER REFIT RIDING HELMET LINER
If a One K Helmet does not come in your size, you can easily change the liner for a perfect fit.
One K liners also provide ultimate flexibility for growing children, shared helmets, or women who wear hair differently for schooling and show!
Three shells make up all sizes.

Love that One K makes these. I swap liners in both helmets once a week. So nice to not have a cruddy, sweat stained helmet, especially in Summer.

I got this to replace my old One K liner for my One K Defender helmet. It's the same size (size small) as my previous one, but for some reason the buttons don't fasten. They just sit loosely in the socket instead of snapping in. Im still using it as it doesn't affect the helmet fit to the point where it's unsafe/unusable, but it's still not ideal. No idea why I had an issue with mine since all the other reviews seemed to be good.
