To improve motorcycle safety many developed countries mandate the wearing of protective clothing by motorcyclists, especially a helmet. Other protective gear may include certain types of jackets, gloves, boots, and pants. Jackets meant for motorcyclists are typically made of nylon, leather, or Kevlar. These jackets typically include heavy padding on the elbow, spine, and shoulder regions. Gloves are generally made of leather or Kevlar and some include carbon fiber knuckle protection. Boots, especially those for sport riding, include reinforcement and plastic caps on the ankle and toe areas. A well-protected motorcyclist will wear boots with heels that fit on motorcycle pegs and provide good ankle support. Pants are usually leather, nylon, or Kevlar. Except for helmets, none of these items are required by law in any state in the U.S. but are recommended by many of those who ride.
