*I have a 63cm ovular noggin.◉◉>**share4.photo/BikeHelmet?Ӊ** Upgrading from my $40 helmet to his feels like a dream. The chin strap is equally as uncomfortable as every other helmet I've used, but the head part is cozy and even has a few cm left over. I know nothing about MIPS, but my order did include MIPS in the helmet.*
