dorianlee Posted November 28, 2011 Share Posted November 28, 2011 I'm playing with the idea of a denali climb next June, and I'm looking for some thoughts on a sleeping bag/ parka situation. Would it be reasonable to use a 0 degree down bag in conjunction with wearing the mighty MH absolute zero parka at night? I've heard this setup is doable, just curious what others who have been up there think. Quote Link to comment Share on other sites More sharing options...
DPS Posted November 28, 2011 Share Posted November 28, 2011 It depends upon the quality of the sleeping bag and how warm/cold it is that year. Unless your sleeping bag is unusually large, it is warmer to drape your parka over the bag. Quote Link to comment Share on other sites More sharing options...
genepires Posted November 28, 2011 Share Posted November 28, 2011 Would it be reasonable to use a 0 degree down bag in conjunction with wearing the mighty MH absolute zero parka at night? This kind of sleeping arrangement is best suited to someone who has considerable experience with sleeping in the extreme cold. It is one of those "if you gotta ask....." situations. Probably not a good way to go for high altitude ventures unless you are doing something like the cassin, but then it is assumed you would have considerable experience in climbing in the denali range. You will get opinions and tales of "when I was there we didn't need anything warmer than a 0 degree bag", but there situation and your possible situations may be completely different. You may find yourself struggling to stay alive while they had a pleasant spring stroll. What do you want to be prepared for? BTW, I didn't need a down jacket on summit day.

dorianlee Posted November 28, 2011 Author Share Posted November 28, 2011 Definitely don't want to rely on it being a warm year, but I will be there later in the season. The MH phantom is one model I've considered. Quote Link to comment Share on other sites More sharing options...
wfinley Posted November 28, 2011 Share Posted November 28, 2011 You'd survive in a zero degree bag - and probably sleep comfortably most nights. But why chance it? You spend a considerable amount of time in your bag in the AK Range and on Denali you'll spend a considerable amount of time in your bag at high altitude where it can be damn cold. Unless you're gunning for a technical route take a fat warm -15 or -20 bag. If you are gunning for a technical route take a warm bag anyways becuase you'll be hanging out at 14 and 17 camp for a long time while acclimatizing and waiting for good weather.

pnwclimb Posted November 28, 2011 Share Posted November 28, 2011 Really depends on the season. I've seen -30 at 17k. That's seriously cold and if you haven't spent a bunch of nights up high AND in really cold temps... you're in for a rough ride taking a light weight bag. That being said... I usually take a -10 to AK for high climbs (Denali, St Elias) and have good luck. Quote Link to comment Share on other sites More sharing options...
dorianlee Posted November 29, 2011 Author Share Posted November 29, 2011 Thanks for the input all. Lots of good points and frosty thoughts to ponder. Quote Link to comment Share on other sites More sharing options...
ASmith Posted November 29, 2011 Share Posted November 29, 2011 I have a -25 with over fill, FF Peregrine (64/60/39) that has been used for less than 7 nights for sale if you are interested. I'm going up to the Snowy Goose for Everest 2012. Email me at Allen(at)livinginswflorida(dot)com. Quote Link to comment Share on other sites More sharing options...

TheNumberNine Posted December 4, 2011 Share Posted December 4, 2011 I was on the mountain for 21 days in June-July of this year. I used the REI expedition -20 sleeping bag and I was comfortable throughout the entire climb, from the airstrip to 17,200 camp. I can't recall ever shivering in my bag at night. For a parka I used the First Ascent Peak 15 jacket and found it to be the best combination of warmth, bulk, style, and packability out of any of the other jackets my team mates had. I would recommend a -20 bag as insurance for comfortable sleeping and safety. Hope this helps. Quote Link to comment Share on other sites More sharing options...
denalidave Posted December 5, 2011 Share Posted December 5, 2011 I would not go back up high in the Alaska Range with nothing less than the best -40 bag. A pound or two more in your pack but good insurance if you get some cold weather. I've suffered with -20 bags enough to have learned my lesson well.

denalidave Posted December 5, 2011 Share Posted December 5, 2011 A lightweight vapor barrier/bag liner is a good idea too. I will never forget the longest night of my life shivering in -55 to -60 below on the north side at only about 10,000 ft. I was thinking, if it's this cold here, what will it be like up high? Turns out, we were MUCH warmer up higher since our camp at 10k was surrounded by 8-10,000 ft walls on all three sides. Still, I'd have paid a fortune to have my buddies CWM instead of my REI -20/pollypro liner/bivy/down parka/booties/mega fleece layers. Once your up there, it's too late to add some fill. Go BIG, I tell ya, GO BIG! Better safe than shiverin all night sorry. Then again, I much prefer heavy and comfy over light and fast. YRMV.

Autoxfil Posted December 5, 2011 Share Posted December 5, 2011 I think FF rents -40 bags. Or you can buy a used one and sell it for about what you paid. Quote Link to comment Share on other sites More sharing options...
