Body Armor Body armor provides essential protection for mountain biking, downhill racing, or BMX riding. Look for lightweight, breathable materials that offer impact resistance while allowing freedom of movement. Key areas to protect include the chest, back, elbows, and knees. Some armor comes with integrated padding, while others focus on reinforced external shields. Ensure a snug fit without restricting your range of motion. Planet Cyclery offers body armor to keep you safe on the toughest trails and courses.
