The Alpinlite would be a good choice if you find standard mummy bags to be too restricting around the shoulders and foot. The continuous baffle means that down can be shifted from the bottom of the bag (where it can get crushed) to the top of the bag for maximum loft. \nWestern Mountaineering says\nThis 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 Alpinlite 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 Alpinlite is just a wide version of that great bag. There are many 20 down mummy bags on the market, but none have the width, warmth, or loft of this bag.\n\nOur Verdict\nWestern Mountaineering down gear has an awesome reputation in the US and that reputation is beginning to build on this side of the pond. Very high quality materials design and construction results in the lightest bags available for a given warmth. \nAn example of their attention to detail is their quoted 850 fill power down used in all their bags: WM quote this figure even though their down generally gets higher ratings in official tests this is because they feel that the official pre-testing preparation enhances the down quality!\nThe Alpinlite would be a good choice if you find standard mummy bags to be too restricting around the shoulders and foot. The continuous baffle means that down can be shifted from the bottom of the bag (where it can get crushed) to the top of the bag for maximum loft. The shifting process is performed by `flicking` the bag in the appropriate direction.\n- Reviewed by Ultralight Outdoor Gear\n\nFeatures\n\nExtremeliteShell\nFull Down Collar\n5 Loft, 20 F\n5 1/4 Spacing/Continuous Baffles\n19 oz.
