Using this karting neck collar is easy. Just put it around your neck and adjust the Velcro strap to fit comfortably. For kids, make sure the 4' opening size is appropriate, and for adults, use the 5' opening size. When you're done with your karting session, remove the collar gently. Keep it in a dry place to prevent damage. If it gets dirty, you can use a mild soap and a soft cloth to clean it. Don't use harsh chemicals or machine wash it as this may damage the collar.
