Next level protection

Created through years of research, MIPS is designed to accentuate the brain's own ability to protect itself and can provide better protection from angled impacts.

Dropping in

Extended coverage at the rear of the helmet not only looks good, it protects more of your head's sensitive areas so you can have the confidence to drop into any situation.
