Designed for your child to wear with another girl’s Spyder Jacket, the ROSIE Pants deliver the snow protection of GORE-TEX and warmth of lightweight 3M Thinsulate insulation. These easy-to-pull on ski pants also feature fully taped seams for the most weatherproof seal. DWR finishes help improve their water-resistance on top of their 10K waterproof fabric. The best feature for parents: the “Great Lengths” hem, which extends by 1 inch, so a growing girl can wear these well into next season.
