Gear Guide 2009: More Summer Sleeping Bags

Extreme Weight-Saver
Think of this hoodless 800-fill down bag as a really warm blanket: perfect for adventure racers and others who like to hike more than sleep. After using it on cold fall nights in the Southwest, testers called it warmer than other comforter-style bags they've tried, but advised that you'll still need to wear all your layers–and warm ones–in temps below 35°F (that's why we deem it a summer bag despite the 20°F rating).

Two removable straps wrap underneath a sleeping pad (there's no bottom insulation) and adjust for body size, clothing, and draft resistance–though it's hard to seal sides completely against the chill. Bottom line: True zealots will love the Ultra's scant weight and liter-bottle packed size, but everyone else will wish it actually was a bag. $225; 1 lb. 3 oz.; 20°F

Down filled and rated to 20 degrees actually sounds a bit hot and heavy for a summer bag, especially in the Southwest, unless you are at fairly high altitude. How about reviews of some very lightweight options such as the Jungle bag from Snugpak, and various bivy sack options and the old military expedient of a poncho with a poncho liner?

"Two removable straps wrap underneath a sleeping pad"

It will actually be warmer if you don't do that but wrap it underneath the body; creates less dead space.
