Fits me, just barely

First off let me start by saying I love the helmet. Great for a little more solid protection than a XC lid. Also according to the reviews I've looked at one of the best helmets of the last couple years. According to the Bell size chart my measurement was a small. I thought this was kind of odd as my previous Giro helmet was a medium and fit great. I ordered the small and when it arrived just like I feared it was just slightly too small. Contacted customer service and they were awesome. They had a medium en route before I'd even shipped them the small back which I did the following day. Once the medium arrived I followed the Bell manual as far as fitting it. Only to discover that on the very tightest setting on the medium it is still just not quite snug enough. I've kept the helmet as it definitely fits better than the small, however just a little loose in my opinion. However this should not detract anyone from taking advantage of the great products and bargains on Sierra. In the future I will just remember that I have kind of an in between helmet size, or maybe just go back to a Giro brand medium.
