High-quality sleeping bag made in the U.S.: Wiggy's (http://wiggys.com). Their "ultralight" 20 degree bag is 3.25 lbs. in regular/regular size, and comes with a compression sack.
The compressed bag is larger and heavier than a down bag, but I chose it for four reasons: very high-quality synthetic insulation; affordable ($130); made in the U.S.; and avoids problematic issues about down sourcing, as discussed by Patagonia here:

Plus, you get all the terrific semi-rants about the inferiority of competitors' products: see Wiggy's news - http://wiggys.com/news.cfm - and commentary - http://wiggys.com/commentary/.
