ASTM F2040 is the most common U.S. certification for snow helmets, covering skiing, snowboarding, and other non-motorized winter sports. Helmets must pass rigorous impact absorption tests in cold conditions and maintain structural strength in freezing temperatures.
For parents, ASTM F2040 is a key sign that a helmet is safe for children and teens learning to ski or snowboard. For advanced riders, it confirms that the helmet is built to handle real-world crashes in terrain parks, tree runs, or backcountry lines.
