ok I know this is a stupid question, but I want to make sure I get a helmet that fits correctly. Ive tried a few on and Im going with an Icon Domain Decay. It seemed to fit the shape of my head well. Heres my question though The XL fits somewhat snug and the L is very snug but not to the point that it feels uncomfortable. Is there a break in period for helmets? I dont want to get the XL just to find out a month or 2 later that now its too big.
