Lovely thick, soft fabric designed to go over our jersey or winter jacket to give you an extra layer of warmth as the days draw in. We have chosen light blue both back and front to give us maximum visibility on darker days but added navy side panels for a slimming look. These weren't on the models but you can see these in the latest sketch. Other features are three pockets to the rear. Saddledrunk, an Italian company, make these for us and, unlike our summer jersey, they are very roomy so best to err on the smaller side (possibly a whole size smaller) when choosing size.
