Looking to get a new helmet, icon death from above. Right now I have an HJC and it XL fits good with a little room for movement. Their chart as well as HJC says I should be in a medium to large.mY head is 22.5 inches 57 cm around. I've tried a large Harley D helmet 59 -60 cm and dam tight.
I'm asking cause I'll being buying it on line. Do you find the next size up to fit better than what the chart says should fit?

 

try it on, everything fits different. I got a Shoei XL and a Icon XL, the Icon is way smaller.

 

Yah definitely go try it on... if your planning on ordering online, go to a local shop and try it on first, every brand fits/feels different..
