Baby, it's cold outside and that's why we created the Baby Snow Pile One-Piece snow suit. It has a supple, 2-layer 100% recycled polyester H2No Performance Standard shell with a waterproof/breathable barrier and a DWR (durable water repellent). The garment is fully seam-sealed to provide extra protection from the elements; THERMOLITE polyester insulation (92% recycled) provides warmth without bulk. Other heat-trapping features include a full-length waterproof zipper with an internal wind flap, and partial elastic at the sleeve and leg openings; this feature also maintains a secure fit over mittens and boots. Tricot lining at the collar, center-back panel and chin guard adds cozy warmth. For mobility, there's a gusset at the rise and an elasticized waist, and an adjustable elastic boot strap keeps pant legs from creeping up. For an additional season of wear, our grow-fit feature in sleeves and legs add 2 inches, and there's a hand-me-down ID label inside. Fair Trade Certified sewn.
