The only problem with this one pound, 30F bag: it didn't keep me warm at 50F. Perhaps if I had been inside a tent with utterly dead air I would have been alright, but even a light breeze rips right through the thin Polarguard, chilling me even in late summer/early fall weather. It's true I sleep cold, but rating a bag 20F too low is ridiculous. I'd have been just as warm with a single layer fleece blanket.
Too bad, since Marmot seems to make mostly quality bags.
