| This 3-season sleeping bag is wide, warm, and packed with features. With a 3-dimensional full down collar, a full-length YKK zipper, and 5″ of loft, the Ascent AcII has quickly become one of our most popular models. Our award winning UltraLite has been a favorite among lightweight backpackers for more than a decade. The Ascent AcII is just a wide version of that great bag. While there are many 20° down sleeping bags on the market, none have the width, warmth, or loft of our award-winning Ascent AcII. | |
