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.
