Lightweight and superwarm, the Nano Puff(R) Jacket is like a baby's favorite snuggly comforter, but with sleeves, pockets and a full-length zipper. Windproof and water-resistant, it 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(R) Gold Insulation Eco (55% recycled) that has a high warmth-to-weight ratio for steady, all-day toastiness. Additional cold-weather features: 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.
