I have an Everest Elite Slumberjack that has served me well for several years. I forget the weight but it is under three lbs. and quite compact when stuffed. It was a steal of a price deal, and a friend liked his so I bought.
It is a little tight on my wide shoulders so I never zip it all the way closed, but I prefer to use any bag like a quilt. It could drape better also, though with age that aspect is improving. I've slept in it when the bag was wet through in places in rainy snow along the 49th parrallel above 6,000 feet on Nov. 1, and stayed warm though a bit steamy feeling. The coldest I've slept in it has been around 0 degree F, but probably was using tear open hand warmers to add warmth at that level of cold.
It is not a top of the line bag but this particular model is pretty good for the price I paid. I know nothing about other Slumberjack models.
