The Stewart Air offers extraordinary ventilation through to the fully perforated front and back and the partially perforated sleeves. The rest of the jacket remains identical to the Stewart, which means the Stewart Air offers style in a basic package. The pull up buffalo leather breaks in nicely with a breath of vintage over time. SEESMART™ CE-level 1 protectors on shoulders and elbows allowed us to keep the silhouette close to casual, while protection can be upgraded by installing our SEESOFT™ CE-level 2 back protector. The detachable thermal liner allows for colder morning rides, and with the liner removed the silhouette can be adjusted using the waist adjustment straps. The short connection zipper enables a connection to REV'IT! jeans using the Safeway belt, and various pockets offer space for keys and documents. Outer shell: pull up buffalo leather.
