Good info as my bag of over thirty years is so thin I couldn't think of cleaning it or for that matter using it another year. I've heard of the Big Agnes too and have my sights on something for next year. I'm one that gets cold easy in my older years and would opt for a  fifteen or twenty degree bag since I like early and later trips besides my summer excursions. Wow though... Looks like a Big Agnus of that temp range is close to a $400 bill if not more. Is cleaning these bags a problem? I'd spend the money if I knew I'd be happy with it. I got a 0 degree bag from Gander Mtn, but it's so big and heavy. Luckily the weather was a lot warmer than usual for my May trip so I didn't have to bring it. Even with a compresion sack it's big. So I'd be interested in any input people have on  Mastertanglers post.
