EverTherm Down Jacket

No quilting. No cold spots. This is down. Revolutionary new Thindown® fabric replaces traditional, high-loft down clusters with ultrathin down sheets, eliminating the need for quilting or channels. It also creates maximum thermal efficiency without bulk and, since the down is uniform throughout, there are no cold spots. You get all warmth, no puff, in a simple, streamlined design that delivers superior technical performance."It's the best jacket I've worn: it's ultralight, warm, and slim."Adrian Ballinger, Eddie Bauer Alpine Climbing Guide (IFMGA), after testing the EverTherm on Mt. Everest
