A motorcyclist is well-protected if they are wearing:

For your protection while riding, it is best to wear a jacket and pants that cover your arms and legs completely. Boots or shoes should be tall and sturdy enough to cover and support your ankles. Footwear should have low heels that will not catch on the foot pegs or rough road surfaces. Gloves made of leather or another durable material will help protect your hands in the event of a crash while providing you with an improved grip on the controls.
