Designed to be part of your clothing arsenal all year long, the ultralight Packable Puffer Jacket sets its sights on maximum warmth and compressibility. The combination of a tough polyester micro-ripstop fabric and PrimaLoft® Silver blended down insulation make for a jacket that is highly compactible. In warmer conditions, the Packable Puffer stows away virtually unnoticed in your pack until called upon to take away after dark chill or an unplanned breeze in the high country. In cold weather it becomes a great mid layer or even a shell if the conditions are dry.
