The MontBell U.L. Alpine Down Hugger Thermal Sheet is designed to fit inside another sleeping bag to use as a winter liner, but serves equally well as a summer stand-alone bag in warmer weather. I like this simple bag's features, baffled down construction and the exceptionally durable-for-the-weight ballistic nylon fabric. My only complaints are a slightly trim fit and that the features add weight. You'll have to decide if the features are worth the extra weight.
Jay Ham started backpacking in 1990 and went lightweight in 1995. Wanting his children to experience and share in his love of the outdoors, he became obsessed with reducing the family's base weight to make backpacking with small children possible. He and his wife began designing and making much of their family's gear (including kid-sized frameless packs and top bags), as lightweight gear was scarce at the time. With a Masters in Soil Science, Jay now manages a 2.5 million acre Soil Survey project in remote Northern Arizona.
