The Big Agnes bags are great! Lots of room to move around compared to other bags. Price is good on these. Havent used below 30 but at 35 -40 these are really warm no need for extra layers .Very cozy
Pad sleeve is great if you havent tried this type of bag it is a great design holds pad in place no matter how much you toss and turn the bag and pad are allways where it needs to be.
