The 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.

• 448g; 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.
• Low Profile Fit
• 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 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.
• 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
• Thermoformed ear pads enhance fit and comfort while improving sound awareness of what's going on around you; 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.
