The Oslo is the benchmark for what a protection-first helmet should be. A lightweight in-mold shell features WaveCel®, an advanced cellular structure that flexes, crumples, and glides to redirect energy on impact. Enhanced BOA® Fit System now adjusts vertically across 8 positions, optimizing how the helmet sits on your head, not just its circumference. Passive ventilation maintains airflow without active management. The Oslo is high-tech made simple.
