Using the Met Downtown MIPS helmet is easy. First, adjust the Safe - T Twist 2 Fit System with one hand to get a comfortable fit. The 360° head belt and adjustable cam navider can be fine - tuned for a more personalized feel. Put on the helmet like you would any other, making sure it sits properly on your head. When riding, the 17 vents will keep your head cool. If you have a ponytail, use the ponytail - compatible vent. You can also attach or remove the visor as per your preference. For maintenance, remove the washable comfort padding regularly and wash it with mild soap and water. Let it dry completely before putting it back. Keep the helmet in a cool, dry place when not in use. Don't expose it to extreme heat or direct sunlight for long periods. And always check the helmet for any signs of damage before each use. If it's been in a crash, replace it right away for your safety.
