The Active Jacket is constructed from our hard-wearing 12 oz Dearborn Canvas. This fabric is now created from 100% organic cotton â€“ but is just as robust as previous iterations. The canvas fabric will soften with wear, creating a fit that is unique to you. This heavyweight jacket also features a mesh lining for increased breathability along with rib-knit cuffs and ribbed bottom band. Triple stich detailing provides added durability.
