Teen boys ski trousers by Stella McCartney Kids, in a striking multicolour camouflage design. The designer's signature logo is printed on the elasticated shoulder straps, which fasten onto the front with clips. These padded trousers are great for high-performance wear on the slopes, with waterproof and windproof features. They fasten with a popper and zip and have zip-up pockets with logo pulls. Made from recycled materials, they have zip-up hems with internal snow gaiters. The Stella McCartney fit can be quite small so choose a size up if you want room to grow.
