If your summer bike tour is going to take you through different climates then the UltraLite is a good choice. With a 59" shoulder girth this efficient bag is good to 20. The full down collar helps to seal in heat around your neck without adding excess bulk, and 16 oz. of high lofting down pumps this bag to 5". The total weight of this very compressible package is only 1 lb. 13 oz.

The MegaLite is cut to suit large folks so they too can enjoy the benefits of the ExtremeLite bags. No claustrophobia here with 64" of shoulder girth tapering to 39" at the foot. 12 ounces of goose down provides a temperature rating of 30, and continuous baffles allow you to adjust the fill to suit your needs. At only 1 lb. 8 oz. this is your best friend during a summer bike trip.

This 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.
