A mainstay in Polo Ralph Lauren 's seasonal offering, the cable-knit sweater never goes out of style, especially when it's crafted from pure cashmere like this grey-green version. The cable knitting technique itself is as functional as it is decorative: the weave is more durable and insulating than standard knitted fabric, making it a truly timeless addition to any collection of knitwear. Shown here with a Hentsch Man shirt , A.P.C. jacket , Folk trousers and Mark McNairy boots .
