Windproof, water-resistant and warm, the Boys’ Nano Puff Jacket performs as an outer layer in cool weather and as an insulating midlayer when things get really cold. Its 30-denier polyester mini-ripstop fabric has a DWR (durable water repellent) finish to shed rain; lining is a polyester taffeta plain weave. A carefully designed quilt pattern holds the lightweight, compressible and 100% postconsumer recycled 60-g PrimaLoft Gold Insulation Eco in place for long-lasting wear. Zippered handwarmers (with reflective webbing pulls) and a tall collar provide additional protection. Other details include an internal wind flap behind the front zipper; spandex binding at the sleeve openings; internal zippered chest pocket (that doubles as a stuffsack) and a hand-me-down ID label. Fair Trade Certified sewn.
