Using your MET Terranova MIPS helmet is easy. First, adjust the Safe - T DUO Fit System to get a snug fit on your head. You can also adjust the vertical position and use it comfortably even if you have a ponytail. The adjustable visor can be set to block the sun or rain as you need. When it comes to maintenance, remove the hand - washable comfort pads regularly and wash them gently with mild soap and water. Let them dry completely before putting them back in the helmet. Avoid exposing the helmet to extreme heat or direct sunlight for long periods as this may damage the materials. If the helmet is involved in an impact, replace it immediately, as its protective capabilities may be compromised.
