- We made the puffer we were looking for. - Down is light as a feather, layerable, and intensely warm, so it’s the ultimate insulation for outdoor adventures. - The shell is made with recycled polyester ripstop and insulated with 700-fill-power down certified by the Responsible Down Standard. - Drawstring closure at hem to keep the cold out. - This jacket's always down to go. The whole thing packs up into its chest pocket.
