Olive Linen Hopsack Sports Jacket, University Stripe OCBD Shirt and a Dry Silk Tie. This jacket is constructed from AIT-056, our own development of a pure linen hopsack that has been washed for a matte olive tone and a soft, lived-in feel. Breathable enough for warmer weather yet with enough heft to last the wearer through Autumn, this is a versatile seasonal blazer, as appropiate with grey trousers and a knit tie as with jeans and a polo.
