Thermal trousers set for teen girls by Stella McCartney Kids, great for layering under skiwear. This set has contrasting red and pink stripes on the front, with blue and green stripes on the back. A signature logo is printed on the top, with a vibrant logo waistband for a designer vibe. Both items are made from smooth recycled jersey, featuring technical fast-drying and breathable qualities. The Stella McCartney fit can be quite small so choose a size up if you want room to grow.
