They may I've never done this before so just trying to cover my bases. I would think a large or xl would fit fine. My snowmobile helmet is xl
Unless something has changed, they should have helmets. @Tim the Plumber, @J.Rex or @RexNEffect All helmets meeting the latest or two immediately preceding Snell Foundation standards (SA2010, SAH2010, SA2005, SA2000, M2010, M2005, M2000, K2010, K2005, K98), SFI standards 31.1, 41.1, 31.1A, 31.2A, 41.1A, 41.2A or British spec BS6658-85 type A/FR are acceptable.
I'm more then likely a LG in a normal helmet I wear a hat in my snowmobile helmet. I'm going to borrow tangles
