I need another option besides my current sleeping bag, it's a 20 degree bag and I know it's overkill for the summer. I do have a army poncho liner that weighs right at 24oz but I'm just not sure it would be adequate. I also have a coleman fleece summer bag/bag liner but I have not used it before. It also weights right at 24oz.

What do you guys think about this:

It looks ok to me, but I don't know light gear like you guys do. Also I am a hot sleeper, most nights at home I kick off most covers and may only use a sheet.

Budget minded suggestions I guess up to $100 would be my price range....give or take.
