Using your Met Echo MTB helmet is easy. Just put it on your head and adjust the straps for a snug fit. Make sure it sits level on your head and doesn't tilt forward or backward. When you're out on the trails, the visor can be left on to protect you from the sun and branches. If you don't need it, you can easily remove it. For maintenance, clean the helmet regularly with a mild soap and water. Don't use harsh chemicals as they can damage the helmet. Store it in a cool, dry place when not in use. Always check the helmet for any signs of damage before each use. If it has been in a crash, replace it immediately as its protective capabilities may be compromised.
