Two pieces handle one job in the Hot Chillys Originals Print Set, a toddler base layer set that pairs a long-sleeve crew top with matching bottoms under the snowsuit. Soft midweight fabric holds in warmth while Moisture Transfer Fibers carry sweat away from the skin, so skin stays drier through a backyard sprint in fresh snow. A close, low-bulk body fit leaves room for snow pants and a jacket on top. What Our Gearhead(R) Experts Are Saying:"Getting my three-year-old into this set takes no negotiation, since nothing scratches or pinches, and the waistband stayed flat under the snowsuit through a whole afternoon of falling and climbing back up."
