They guys at Woot are offering the High Pak Lite Peak 20-degree Sleeping Bag for just $19.99 shipped today. If you do much shopping for camping gear, you know that a $20 sleeping bag that weights under 3 lbs. is hard to come by. These sell for $35 or more elsewhere and the High Peak brand gets solid customer reviews everywhere I looked. If I had to gamble, I would bet these won't last all day.
