One-way hinge back design is comfortable on bike, but does not compromise protection. Foam shoulder pads add protection. Removable upper arm guards. Internal Bio-Foam areas are strategically placed for maximum comfort. New Matte finish adds a distinctive new look to the Defender line. YOUTH: 4'1"-5'4"/65-120lbs.
