AFX FX Magnus Helmet 4 5 5 5
Size is a step down I bought a xxxl thinking it would fit after I measured my head circumference at 25.5. Helmet fit tight around cheeks, breath guard pushed against my nose and my chin hangs lower than the bottom chin. Used so can't return. Needed xxxxl August 18, 2014
Great product. Super good buy for people like me with a giant dome piece. September 24, 2013
Slightly dissapointed but not a lot of selection I have a very big head so this was my third attempt at getting a helmet. I ended up getting a 4XL even though my head only measures about a 25". SO not exactly true to size but I got it figured out. Within an hour of riding it it had chipped on the back of the helmet which was disappointing. It also is not well vented. I am a sweaty person in general but even at cool/highway speeds it's still sweaty. August 10, 2013
Seems to be a good helmet for the $. I have had 2 AFX helmets and use them because I get the best fit. June 10, 2012

RevZilla Store asked: Why did you choose this?
Cam W: Was the only helmet that fit. But I do like it. Wish it was a tad more breathable and looked a little cooler but I enjoy it. May 20, 2015
A shopper asked: I am trying to decide between an HJC CL-Max 2 4xl and an AFX FX Magnus. My question is, how different are the shapes of these two helmets? I have tried on the HJC CL-Max 2 and it is a comfortabe fit, but I have not found an AFX FX Magnus to try on to compare. Seeing as I have a large noggin, these are about the only two helmetsa that I have found in sizes that will fit my head. Any information would be greatly appreciated! Dec 2, 2014

Cam W: Me personally I tried both and the HJC cl-max 4xl did not fit me. I have had no problems with my AFX fx magnus and it is quite comfortable on my noggin. However I do feel that the hjc looks cooler. I would say that if the hjc fits, go with it as the AFX helmet is for extremely large heads and it was my only option. Good luck and merry Christmas Dec 2, 2014
