Shift leather jackets use 1.2-1.4 mm full grain leather for the best protection. The Octane is no exception. CE approved armor with a pocket for the foam back pad provides impact absorption to reduce injuries. A leather jacket without perforations is impractical, Shift perforated the lower torso for cooling. If temps drop down, a Soft quilted liner will keep the chill out. Riders looking to ride in pants can add a pair from Shift by attaching them with the integrated zipper. Versatility in design makes the Octane a great all-season jacket that can do almost anything.
