First question:

What is your price range?

I have an Alpine 20 from Sports Authority.

It weighs 3 lb 4 oz including the stuff sack and a plastic bag.

I used it last year in Colorado. I was given a diffent bag this year, but my son still uses his. Neither one of us uses a pad under the bag.

We are comfortable down about 25 degrees in them. But that's with extra clothes on and we both sleep warm.

So far the bags aren't showing any signs of wear and we have been out a lot.

Right now, it's on sale for $29.99. It's marked down from $59.99.
