Lots of air moving through this helmet, and the fit is very adjustable.

Takes some getting used to.

Scored one of these off Chainlove for a nice price. Looks great, but have not tested it in an actual crash yet. (Hope to never test it in that way.) The liner and strap system are very adjustable, and I believe this helmet has the most adjustable fit of the Met helmet line: the so-called "Safe-T Smart" helmet liner. It has a wheel on the back for adjusting tension around your head, plus you can adjust how high/low the front of the helmet rides above your eyebrows. My head is about 58 cm in circumference, and a large fits well, leaving plenty of room for the folded cotton bandanna I use for sweat control. In sum, it seems to deliver good fit, good airflow, and looks fine.
