Uvex’s octo+ fit system is the biggest draw of this helmet. Imagine a soft, fuzzy octopus wrapping its tentacles around your dome… yes, the system’s stretchy wrap-around strap and flexible “fins” engulf your head for a perfectly adapted fit. There’s also a smidge’ of space between the EPS inner shell and octo+ system, allowing for fresh air circulation that’ll help to cool you off during periods of intense activity.
