Using this helmet is easy. First, adjust the Safe - T Twist 2 Fit System with one hand to get a snug fit. The 360° head belt and adjustable cam navider can be further tuned for a personalized feel. Put on the helmet and make sure it sits comfortably on your head. If you have a ponytail, use the ponytail - compatible vent. You can attach or remove the visor according to your needs. When it comes to maintenance, remove the washable comfort padding regularly and wash it with mild soap and water. Let it dry completely before putting it back in the helmet. Store the helmet in a cool, dry place away from direct sunlight. Avoid dropping or hitting the helmet, as it may damage the MIPS - C2® brain protection system. If you've been in an accident, replace the helmet immediately, even if there's no visible damage.
