Alright so question here, a group of buddies and myself are going to go winter camping in the BWCA in late Feb. We are renting a canvas tent with a stove, so should get nice and toasty in there, question is with that type of tent, do you all think that I could get away with my normal 40 F bag and some blankets? I am just thinking of weight for my back and space in the sled. I have a big sleeping bag that is rated to -30 F but weighs 12 lbs its huge...... just trying to see what i could get by with let me know guys thanks!
Ya, we will just canoe in Lake Superior.

Unless above freezing for the ambient temp outside-- NO.
The canvas tents warm up nicely when the fire is going-- when the fire goes out-- the only thing between you and the ambient temp outside is maybe five degrees of canvas heat island and your bag.
By the time you add up the weight/bulk of your 40F bag and enough blankets to stay warm at say -10F--- you might as well bring the beast rated at -30F or wake up every 2 hours or so and stoke the fire which wouldn't reccm.

I've never actually used a stove / hot tent myself, so as a cold camper I'm going to say you should have a sleeping bag that would at a minimum keep you alive (if perhaps uncomfortable) if for some reason you couldn't use the stove at all. Going out with only a 40-degree bag sounds like a really good way to end up on the news...

This is the exact question I had when I first got into hot tenting. I initially thought I'd be toasty warm all night long and that I could load the stove with wood before going to sleep and it would burn slowly all night long. Well after 2 hours the stove goes out and the inside of the tent is the same temp as the outside. I went out and bought a bag rated to -60 (I know it may be overkill but I get cold at night) and it works great in the hot tent once the stove goes out. So I agree with the other posters here in that you should opt for a warmer bag. Can you rent a bag from the same place you are renting the tent?

a 40 degree bag is probably pushing it. The temps in late Feb can get just as cold as mid Jan. We were camping the last week of March and we had temps as low as -17. As mentioned above the heat from the stove is only going to last so long, even if you have quality wood it will keep the tent warm for only an hour or so if temps are below zero.
Another thing to consider is getting yourself off the ground. To be honest the sleeping bag I use is only rated to 0 but I also have an exped downmat that does wonders. We were up the gunflint last December and it never got above 0 the entire time we were there and the people at the outfitters where we left out vehicle said it was -20 each night with one night getting close to -30. I slept well each night and I believe getting up off the ground a little bit made a huge difference.

I was there then too...what a difference a year makes eh'?

No, your 40 degree bag is a bad idea. I view my sleeping bag/system as part of my survival gear. You need a bag/bags that will handle the cold, period.

Just to add to this...in my opinion a decent sleeping pad or pads is just as important as the sleeping bag. You'd be amazed at how much heat gets sucked out of you from underneath

Bring that 40 degree bag...probably rectangular?...put it outside of a lightweight compact 15 degree bag. Still way under the bulk and weight of your 12 lb monster. You should be ok. Good mat makes a huge difference.

Until the second night.

For even better insulation from the cold ground, use a closed cell foam pad, they are light and very cheap and will definitely increase the effectiveness of an isulated Big Agness aircore, or exped. I'm speaking from experience from not, and then to, using one on nights it was around -10F and the round was just as cold (I was cold camping). The closed cell pad made an amazing difference.
12/23/2014 11:44AM
I meant to say, put the closed cell foam pad on top of Exped or BA aircore. Place it right under your sleeping bag for the best performance. I tried putting in on the ground first, but found out that it works best, by being on top of the other pad and just under you.

I love my snowtrekker and four dog stove but sh...tuff happens and if you get wet during the day (far from your tent or tent isn't set up), have a tent fire at night, run out of or can't collect enough wood you'll be sorry or dead if you don't have a warm enough bag. two bag systems work great. doesn't hurt to try it out in your backyard or screen porch on a cold night. agree with the advice on a good pad. Exped downmat FTW! But because I always worry about the worst case scenario and pack redundantly I also carry a closed cell foam pad or roll of reflectix.

my bag is rated at 0F, one night I survived -25F overnight temperatures by doing sit ups to warm up after waking up cold every 2 hours, I had gone to sleep about 7PM, so it was a VERY long night, morning seemed to take forever to come

This is a classic reason why you get the best bag you can or go to a cheaper double bag system. There's been times where I was cold but if I can throw anything on over my bag/bags it saves me. One year I left my inner bag home what a mistake.

Don't trust the rating that the bag manufacturers put on the bags. Only a few manufacturers have true en ratings. The ones I know of are marmot feathered friends and western mountaineering. A true 0 degree down bag will have over 3 1/2" of loft on the top. 4 1/2" for a minus 40 bag.
My marmot has a full inch more of loft than my friends mountain hardware of the same rating. I especially dont trust any ratings of synthetic bags. I have never seen one perform even close to the ratings. A liner is good for a little more warmth also.
I just spent the weekend in the bwca sleeping in -20 temps in a 0 degree bag and was toasty warm.

Your sleeping bag is one of if not the most most important piece of winter camping Don't cut corners at that end.
Also much can be done on what you wear to bed,a balvacada or other similar hat and your layers of close you wear to bed.
Also have good insulation underneath.
Even cold camping I believe your tent can add 10 degrees warmth in how it is utilized. The right combination of aeration to prevent frosting and trying to hold your warm air in is critical.
