Mikewrote a review of Red Commander Helmet on March 8, 2013
My head measures close to 57CM and I find that the Medium fits perfect. I also have a smith vantage helmet and the Vantage is a tad lighter on the head but this helmet is not by any means heavy. I got this helmet because the vantage in matte white just looks too much like a bike helmet for my liking.The profile of the Commander is not bad either and I've attached a pic to show what it would look like if you're on the slopes. Not super low profile, but definitely not the bobble head look either.
