Im comparing sleeping bags for warmth and quality . Im interested in synthetic filled bags only . Im also interested in a - 20 degree bag . I've been checking out the Mountain Hardware , Marmit , North Face and Out-door Research .
There all good names . I thought the North Face had a little bit more room since all sub zero bags are mummy style . Undecided . I heard Mountain Hardware was a excellant bag , but that was from a sales person .
