This new Double Layer unisex sweater inner layer is made from a very soft cosy thin fleece and the outer layer is made from a stretchable easy care material with breathable side mesh panels. Available from size S-XXL. The sizing is quite neat as the garment is unisex. So if you are a man and you normally take a medium we suggest you take a large. If you are a lady and you normally take a ladies medium then we suggest you take a medium in this sweater!
