This sweatshirt is an ideal mid-layer option when it\u0092s too cool for a t-shirt but not cold enough for a jacket. Made in a sustainable polyester\/cotton fabric, it has a modern slim fit and 4cm tape gap on the side seams, allowing the garment to stretch and providing maximum comfort for the wearer.
