The Canvas Jacket in Grey from AJS, Australia.  

Details
Woven from cotton hemp for a soft, breathable feel that only improves with wear.
Cut with a boxy body and dropped shoulder, the sleeves extend to meet the palm for a considered, elongated line.
Cut from a heavyweight cotton canvas with a substantial hand that softens with wear. Lined in satin with a metal zip closure for a refined, considered edge. Panelled construction through the body and sleeves for a clean, structured drape.
Hand sewn in Bali.
Fits true to size
