Filled with lightweight, 100% recycled body insulation, the Baby ThermoBall™ One-Piece is the ideal all-in-one layer for their first few winters. With an attached hood, fold-over mitts and booties, plus a water-repellent finish, they’ll have the coverage they need for new adventures in the outdoors. This has been worn but in great condition. This fit my kids until they were age 3, seemed to run a little big.
