- This is a men's woollen jacket. It's made from a comfortable cotton mix. Sleek, almost unnoticeable zipper on front. The model is wearing size L and is 187 cm tall. JACK & JONES CORE Very nice woollen jacket to throw atop everything from formal wear to jeans and a T-shirt. It's got both a windguard and hood, so you can feel safe from the most daunting of winds you'll come across. The front is detailed with a pocket and a minimalistic zipper. Useful but elegant.
