Helly Hansen Kid's Legendary Pant Ski trousers Kids (16 Years, blue) - The Kid's Legendary Pant by Helly Hansen are tough and also offer optimal protection against bad weather on the piste! Helly Tech makes their material fully waterproof and windproof but also breathable. Moisture from the outside can’t get in, while moisture inside is rapidly wicked away, which helps to make the trousers comfortable. The synthetic PrimaLoft insulation is reliably warm, even in wet conditions, so kids are well prepared for icy days.
