The legs of the Ski-Doo Kids' X-Team Highpants snowmobile pants can be extended by up to 4" (10 cm) as your child gets taller. With a fleece-lined full front and back bib and critical seams sealed, these kids' ski doo pants are windproof, waterproof, breathable. Shaped and reinforced knees make them durable. A Velcro† adjustable suspender system and waist, and elastic waist at the back mean these snowmobile pants will keep growing along with your little riders.
