Lightweight and superwarm, the Baby Nano Puff Jacket is windproof and water-resistant and handles fickle climes by combining a 1.6-oz 30-denier 100% recycled polyester mini-ripstop shell and a 100% polyester plain-weave lining, both with a DWR (durable water repellent) finish. In between there’s ultralight, compressible 60-g PrimaLoft Gold Insulation Eco that has a high warmth-to-weight ratio for steady, all-day toastiness. Additional cold-weather features: full-length zipper with internal wind flap and zipper garage, zippered handwarmer pockets with reflective pulls, and stay-put spandex binding at sleeve openings and hem for a secure fit. Hand-me-down ID label. Fair Trade Certified sewn.
