Review on Smith Optics Adult Snowmobile Helmet by Ronnie Polk

husband did not fit. We ordered size XL. His head size is 63 inches and he should be up to 67 inches tall. It was too tight at the top of the head. It doesn't have dial adjustment, but it does have strap adjustment. It hit him in the back of the head. Finally returned it. The helmet looked like it was of great quality, it just didn't fit him at all. I recommend trying it on in store before ordering online to see if it suits you. The seller's customer service was excellent.
