This lightweight puffer jacket's made with a PrimaLoft® padding. It's super warm and insulating, and doesn't get heavy when it's wet. It's also perfect for layering under thicker coats and jackets. It comes with zip-up pockets, raglan sleeves and internal pockets to keep all the valuables. It's also been designed to act as a liner for our Dales Waterproof Jacket, so it'll be super warm.
