MASTERPIECE: Ultra Light Down Jacket Surprisingly light. Incredibly warm. We've developed a specialized material woven from high-density nylon thread, a tenth of the thickness of a strand of hair, to provide lightweight airy warmth. Because of our use of premium down at the golden ratio of 90% down to 10% feathers, the jacket stays thoroughly warm despite how light it is. Our Ultra Light Down products also come with storage pouches they can neatly pack into, providing versatile warmth on the go. #UltraLightDown #FallOuterwear #DownJacket #UniqloUSA #LifeWear
