The Kids' Anon Oslo WaveCel Ski & Snowboard helmet is built around WaveCel's revolutionary WaveCel® structure, which flexes, crumples, and glides to reduce both impact force and rotational energy in a crash — addressing the leading cause of concussions in snow sports. Combined with Anon's precise-fit system and excellent ventilation, this is the most safety-forward helmet in the lineup.

• 444g; WaveCel helmets are designed to fit closer to the head, providing a snug, comfortable fit. Please refer to our sizing chart for accurate measurements. If you are in-between sizes, you may want to size up.
• 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 shell construction fuses a lightweight polycarbonate shell with an EPS liner for a low-profile fit
• Passive ventilation channels, highlighting WaveCel material through 10 vents, help draw fresh air in the front and pull moisture out the back
• 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
• Fidlock® snap helmet buckle uses magnets to allow you to open and close the buckle with one hand even when wearing gloves
• Snow stopper fabric retains warmth and comfort for cold-weather conditions while preventing snow from entering the vents.
• Compatible with audio accessories
• All Anon products are backed by a 1-year warranty from date of purchase. Anon helmets are also backed by a 2-year crash replacement policy.
