"What Our Gearhead® Experts Are Saying: ""I switched to the Oslo WaveCel for its lighter feel and sleek fit, and I’m sold. The BOA fit system is super precise, and the WaveCel tech gives me serious peace of mind. Plus, the fleece liner is incredibly warm without getting sweaty on bootpacks. It’s low-profile but totally high-performance.""When protection, comfort, and weight all matter equally, we trust the Anon Oslo WaveCel Helmet to deliver. Its low-profile silhouette blends seamlessly with any goggle setup, while inside, WaveCel technology forms a 3D cellular structure that flexes, crumples, and glides to absorb both direct and rotational impacts. Paired with an in-mold EPS shell for lightweight durability, this helmet features a 360° BOA Fit System for precise, on-the-fly adjustability. A Fidlock magnetic buckle lets us secure the chinstrap with one hand, even with gloves on, and two passive vents keep air flowing to reduce goggle fog. Finished with a plush fleece liner and earpads that wick moisture and hold warmth, the Oslo is built for riders who expect both high performance and dialed comfort every run."
