Hot Chillys MTF Tight - Girls':  If you’re looking for classic kids’ thermals, look no further than Hot Chillys® Originals II. Improving on the qualities that made the first generation so popular, this update has since become a classic in its own right. Their success lies in an ideal warmth-to-weight ratio that won’t leave your child shivering in the cold, but also won’t have him looking like the Chillsbury Snowboy. Originals II will also keep your kids snug and warm with a body-fitting stretch that goes wherever they do.
