EXCLUSIVE AT MR PORTER. Launching Howlin' came naturally to brothers Messrs Jan and Patrick Olyslager - their parents started a knitwear label back in the early '80s, so they've grown up in the business. Designed exclusively for us, this sweater has been expertly knitted in Scotland from a mid-weight lambswool and cotton-blend. The 'Ocean Blue' shade looks really nice with neutral colours, like beige.
