Try the IRH ATH SSV helmet. IRH makes several helmets that come in actual sizes (not the dial fit) and are available in long oval. Also they are ASTM SEI approved. I have one in long oval myself and it’s probably the best fitting and most comfortable helmet I’ve ever owned. Not to mention the price is still somewhat reasonable (but we are talking about protecting our noggins here, so can’t be too picky with cost). I hope this helps.
