WaveCel® Technology – WaveCel® behaves like a network of hundreds of interconnected shock absorbers connecting your head and the outer shell of the helmet. WaveCel® helps distribute the impact energy through its network of cells, reduces impact forces like the crumple zone of a car, and then helps divert rotational forces by flexing and gliding.

In-Mold Construction – In-mold shell construction fuses a lightweight polycarbonate shell with an EPS liner for sleek comfort and a low profile fit.

Passive Ventilation – Passive ventilation channels, highlighting WaveCel material through two vents, help draw fresh air in the front and pull moisture out the back. Snow stopper fabric retains warmth and comfort for cold-weather conditions while preventing snow from entering the vents.

Round Fit – Consult the size chart for measurements

360° BOA® Fit System – In-Shell 360° BOA® Fit System integrates a fit dial directly into the helmet and provides for micro adjustments in a complete halo around the wearer's head

Anon x FRAGMENT – The Anon x FRAGMENT Oslo WaveCel Round Fit Helmet features a limited-edition Hiroshi Fujiwara stealth theme.

Fidlock® – Fidlock® snap helmet buckle uses magnets to allow you to open and close the buckle with one hand even when wearing gloves
