Good quality stuffsack. My old one went missing and I needed a replacement. This one should work fine. A little large for a 20 degree bag - but then again it compresses. I bought it mainly for my winter -30 down bag. Might be a chore to get it in there but I believe it can be done, especially if I eat a protein bar or something before hand. Anyway, yes this bag will due just fine for making your sleeping bag smaller.
