Rated 5 out of 5 by from 35 years of cycling - best helmet ever Bought this helmet four months ago - it is light yet still feels substantial enough to protect. Literally does seem to cut through the wind, lot less noise as well, as advertised. Realize it is expensive, first time for me leaving the $120 helmet zone. The MIPS is great and super comfortable. Easy money for bike safety and frankly it makes me feel like a kid again - riding without a helmet - except I am wearing one. One other thing, the silver lined mesh right over my forehead - thought was gimmicky - actually works - keeps sweat out and doesn't smell bad :)

Will this helmet slide up in the front when wearing a cycling cap or beanie? Or will it stay firmly in place?

Asked by: David
​The fit will vary based on your head shape and the thickness of the cap/beanie.
