What is the size of this particular helmet? When I'm ready to purchase, can I get XXL, 63-64cm which is the size of my current GMAX helmet?

it should give you the option to chose the size. If not contact the seller to make sure they send you the correct size!

Giro.com has a fitment guide when you go to buy a helmet. 55-59 is size medium.

They are dial adjustable. Mine is an XS/S and fits 51-54 cm. If your head is more oval shaped than round shaped you will probably like this helmet.

I bought a size large for my 6'3" husband & wanted a design on the helmet. I think the design was what cost so much in my case. I am not able the compare the products you are asking about but if the same company makes both helmets then I would think the difference is the seller(s) description; one seller wrote out the size and one seller is selling for much more. Sorry - probably not very helpful. Good luck.

not sure on exact measurements. A legal size authentic helmet is what is on mine and fits just fine.

I don't know the exact numbers, but the outer dimensions are the same as the current large size PASGT helmet worn by U.S. Marines. http://www.gentexcorp.com/assets/base/TechnicalPublications/PadSuspensionSizingChart.pdf

The best thing to do is to go into an actual store and try on the helmet to figure out what size fits you best...then order it at a better price from Amazon! Watch a youtube video on helmet safety and proper fit!

tough question because every company has their own sizing chart. If you haven't already, check their website for a sizing chart. I ordered a Medium. It has an adjustment that is easy to use with the helmet in place. The range of the adjustment is pretty impressive. It can go so small that there is no way I could possibly get my head in it, and yet it can get so big that it would easily fall off of my head. My head is 22.5 inches around (just above the eyebrow). That's the best I can do.

There is also an Amazon.com Bike Helmet Buying Guide. I was right in between medium and large. I chose large. To make sure, there was a bike shop at the University that sold Berns (much more expensive there) and I tried on both M and L.

I have a small head (like a child). Mine measures 22" also. I got the Small/Medium & it fits great. I really love this helmet. & I love the "dial" in the back so once you get it on, you dial a few clicks to get a nice snug fit, or un-dial a little if it's too tight.

My son and I use medium, it fit slightly tight, but it fine with us as the one we have before was also a Bell medium different model and it was too lose. If it is uncomfortably tight get the large. Not sure what your using the helmet for, we race BMX and if the helmet move it interferes visibility.

Aha! I went online and researched - take a tape measure around your head at forehead level. Mine was like 24 inches I think. Convert that to centimeters, as most helmet sizes are cm. Then there are guides online that equate inches to helmet size - see website below (http://www.telemarktips.com/HelmetSizing.html)

Normally the Helmets size are in cm, for example my size are XL which is 60 to 62 cm, in your case this helmet can by OK for you due to the IV2 helmets is normally smaller than other Brands
