Kutenay, all good advice, but I fear Ryan is just a troll or a teenager who's got no clue of backpacking to start with. Why else would he repeat his idiotic statement, "can't I just use a Colamen 0F bag" <img src="/forums/images/graemlins/tongue.gif" alt="" /> It's folks like him who find out how tough the outdoors can really be in any Season, let alone Winter, which has killed experienced outdoorsmen many times.

I for one appreciated all the posts that gave valid information on the subject. Winter is as someone said, "No place for cheap gear, your Life depends on it"... I could'nt agree more.

Marmot's 2 high end 800fill down bags a -20F and -40F are nice quality but not cheap either.
