The First Light Jacket is a do-it-all mid layer or outer coat, designed for adventures that range from crack-of-dawn touring missions to springtime treks. It features baffled and migration-resistant PrimaLoft Silver Insulation Active, delivering hydrophobic and packable warmth without the bulk. The face and lining fabric are made of airy and robust stretch woven fabrics, which allow maximum mobility and breathability. Black Diamond outfitted this jacket with gusseted underarms to enhance movements when climbing. They also gave it a low-profile, single-hand adjustable hem. The First Light Jacket stuffs into its internal chest pocket and attaches to a pack or harness via a carabiner clip loop.
