A durable jacket and pair of pants are a no-brainer when you’re shopping for gear, but you should never overlook the importance of elbow and knee pads. A lightweight pair of guards with protective shells and foam pads is enough to keep you safe on the road without feeling bulky. If you have the extra cash, get yourself some back armor as well so you’re protected from head to toe.
