This is a great helmet, very high quality, and Revzilla's video was definitely informative. Quick delivery too. I ended up being exactly half way between a small and a medium (I measured in at 22 and 1/4"). I went for the medium, and even then it is a bit snug. I'm sure it will break in to exactly the right size for me, but if you are halfway between two sizes, DEFINITELY order the larger!
