Amply insulated with 700 fill goose down, this iconic vest is extremely warm, lightweight, and highly compressible for travel. Ideal as both a stand-alone layer in cold conditions or as a layer underneath a waterproof shell during cold rain showers, this high loft down vest features sewn-through construction that keeps down shifting, eliminating cold spots. Double taffeta layer at shoulders increases durability with backpacks, and hem cinch-cord provides a buffer to ward-off upward gusts of wind. Updated for 2011 with a modern, slim fit.
