Using your Bell Sixer MIPS Fasthouse Trail Helmet is easy. First, adjust the Float Fit system to get a comfortable and secure fit on your head. If you're wearing goggles, use the strap gripper at the back of the helmet to keep them in place. You can also adjust the visor height according to your needs. When using a camera or light, attach it to the integrated mount. As for maintenance, use a mild soap and water to clean the helmet. Don't use harsh chemicals as they may damage the helmet. Make sure to let it dry thoroughly before storing. Check the helmet regularly for any signs of damage, like cracks or loose parts. If you notice any issues, stop using the helmet and consider getting a new one.
