Sea to Summit - Spark Sp III

For fast-and-light backcountry travel, Sea to Summit's Spark Sp III packs down incredibly small and provides 3 seasons of lofty warmth. Its Ultra-Dry Down® 850-fill goose down insulation resists moisture in damp conditions, and a featherweight Pertex Quantum shell also helps keep your bag dry. Thanks to this ultralight fabric and 1/3 length zipper, the Spark packs down to an amazing 9 by 5 inches. You won't find this much warmth for so little weight in many other bags. This is a great choice for adventure racing, summer backpacking, even international travel.
