Mutant Size:Large and reinforced structure ensures stabilityMutant is an ultra lightweight helmet for mountaineering and climbing Expanded polypropylene (EPP) construction provides effective impact absorption with reduced weight, while an ABS reinforcement on the top increases resistance in high exposure zones. Its structure protects both the top and sides of the head while maintaining consistent airflow. A minimal adjustment system reduces bulk and allows compact storage. Multiple sizes ensure a precise fit.
