Review about the Icon Airflite Rubatone motorcycle helmet №8527

"The helmet was much larger in size than expected.. It feels like 3 times (or maybe 4) more than the volume of the head. Most likely, the shell of this model is the same, but only the size of the internal inserts differs (this is my first helmet). I would recommend it to big riders."
Do all helmets have the same shell ? how much bigger does it look when compared to Icon Airframe Pro Rubatone
and tell me what weight, I can't find anywhere, it's not very convenient..
