The North Face, Mountain Hardware. Both not bad, But there not Marmot, and they sure as hell don't have a Col

Super good bag!! Kept me warm to -30 on Denali this summer. The zipper does snag a bit, but don't they all.

This is a winter bag for all of the continental USA. Marmot has made excellent bags since the penguin became a classic! It has kept me warm at -20 and is built to last. The Dryloft covering is able to keep the down dry in a frost covered tent even while cooking!

Marmot will do what it takes to make you happy.

The North Face Inferno Dryloft is about as warm although rated to -40.

This bag is worth the money for Rocky Mountain Climate. I have used it above 12,000 ft. without a tent in Nov/Dec and it kept me toasty warm and the strong gusty winds didn't come close to getting through the Dryloft shell

This is a dynamite bag with a ton of features. The bag is roomy in the upper torso for easy manipulation of the draft tube and hood. The hood fits better than any other mummy I've tried. The loft is superb. I love the Dryloft coating...not having to worry about wet down. On a recent snowcamping trip, my bag was the only dry one after 2 nights with a couple other tentmates. The temp rating is conservative...read as accurately represented. I have yet to be cold in this bag!!
I LOVE THIS BAG!! Plus I found it at a great price at an online outdoor store. I would of had a hard time spending full retail, but the value is definately there.

Great Bag! Has kept me warm on Denali and some very nasty nights in the Park (Rocky Mountain National). Dry loft is helpful for both wind - and the cup of tea your partner spills in the tent. Bag is cut big enough for extra water bottles and equipment.
