Google found a couple of reviews, but they were about using it as a snowmobile helmet, since that's what it's designed for.

I could tell you about the helmet I bought, a Capstone Sun Shield II H31 Modular Helmet, but I bought it because I wear glasses, and it's got features built in that are designed for someone who wears glasses.
The only thing I don't like is that it's "Gauntlet Grey" in color, and my Spyder is white.
