I've only worn these a few times because my child quickly outgrew them. These insulated outer pants are perfect for playing in the snow or as everyday cold-weather wear. The insulation uses Exceloft®, a synthetic fiberfill that is warm and easy to care for. The pants have a deep rise and inner gaiters at the cuffs to prevent snow from entering. The waist uses both a belt and elastic for easy on and off. They can be washed at home if they get dirty. *These are not waterproof.
