This two piece thermal underwear in grey and blue with dinosaur print wraps kids in cloud-soft warmth that feels like wearing a hug under their winter clothes. The brushed polyester base layer set glides on smoothly with a half-zip top and elastic waist pants that move freely with every snow angel and sled run. Super soft against skin with mighty dinos stomping across the fabric, this cozy foundation keeps the cold out while letting active bodies breathe during all-day winter play.
