If you're looking for classic children's thermal, look no further than Hot Chillys Originals. Improving on the qualities that made the first generation so popular, this updated thermal underwear has since become a classic in its own right. Made with comfortable micro-polyester fabric, this thermal is designed to last through multiple washes while providing the softness and breathability your kids need to stay warm and active.
The success of Originals lies in an ideal warmth-to-weight ratio that won't leave your child shivering in the cold, but also won't have them looking like the Chillsbury Snowboy.
Your kids will be snug and warm with a body-fitting stretch that goes wherever they go.
