[Made To Last: The shell lining and trim on these boys and girls Snow-armor Squall pants are made from 100% nylon. The light insulation is made from 100% polyester, which helps trap body heat. Easy Breezy: These midweight reinforced snow pants are a snap to wash. Toss them in the machine, and they'll be clean again in no time. Unlike some waterproof outerwear, no special care is needed. Total Comfort: We added a partial elastic waist to these snow pants so they have plenty of give and feel extra comfy. There’s also a zipper fly, so your little one can quickly put them on and take them off. Design Features: The body-hugging fit traps warmth while still being easy to move in. Zip ankles pockets provide storage space and elastic snow gators keep wet stuff out." Rugged: The Iron Knees and Seat in these casual snow pants are fully reinforced, while the Grow-A-Long legs also extend up to 2 inches. Kids can wear them sledding and playing in the backyard.]
