Made with PrimaLoft One insulation (4 oz. in the body, 3 oz. in the sleeves and hood), 1.9oz rip stop with DWR as the shell and a light taffeta liner with DWR. The jacket features a simple and elegant design with hand warmer pockets, stretch pockets for gloves on the inside and a chest pocket (which will be a bit smaller than the one pictured in this sample). It currently weighs in at around 22 oz. but we suspect that the weight in the production model will be a bit less. All the materials are sourced domestically except for the Riri Aquazip main zipper which comes out of Italy. We're very excited about this piece.
