Designed to be part of your clothing arsenal all year long, the Packable Puffer Hooded Vest sets its sights on both warmth and compressibility. The combination of a tough polyester micro-ripstop fabric and PrimaLoft® Silver blended down insulation make for a vest that is highly compactible. In warmer conditions, the Packable Puffer Vest 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.
