Recieved the Kelty Light Year 20F and Mtn Hardware 32F bags today. Tried both and think I like the Kelty better. Sure it's 1 lb heavier, but seems better made and more comfortable overall. I think I would go with the Mtn Hardware bag except the zipppers (2) only go about 1/3 way down on each side, and got stuck several times already.

I wanted to like the Mtn Hardware better though. Another thing, there was not much chance of getting it in the included stuff sack!

Last question, will a 20F bag be too hot? I tend to sleep hot, but I know once temps go down at night most of us like to stay warm...what's a typical comfortable range for a 20F bag?
