What temperature rating do most of you use for winter camping? Are you using 0, -20, -40 or what in the way of down sleeping bags?

I have an old 2 bag system of synthetic bags. One bag was rated at -20° and the other bag's rating maybe is a 5° bag but I forget. The warmer bag fits easily into the -20° bag.

I'm looking at using a 15° down bag along with a down quilt 20° over it if I can make it work.

Your sleep system is something worth spending extra money on. Ratings are so subjective and bags lose their ability to maintain their ratings (especially synthetic bags) for many years unless well taken care of.

I have a 10 degree down sleeping bag that sleeps hotter then that and I stuff that into a 20 degree synthetic bag that also sleeps warmer. Having those two and a hot tent has been perfect for me.

BigAgnes PomerHoit down, 2 1/2 pounds, 0 degree rated. Exped Downmat9, 2 1/4 pounds, R value 8.

Slept in long underwear and balaclava below zero (single digits), comfortably! Double digits below I will add (outer layer), synthetic 20 degree REI bag.

I have a 10 degree bag and use an exped downmat 7. I haven't had any trouble staying warm so far but the coldest temp I have slept through was -28.

This is my route as well for bag ratings...just different brands on the bags...and no down.

I've used a two bag system with good success. Both bags are I think 15°F bags, but one is old and undoubtedly closer to a 25° bag now. I sleep warm, and so far am good down to about -20°.

0 degree marmot never summer down bag. It is en rated at 0. Make sure and look for the en rating as it is much more accurate then some brands made up numbers. Another way to figure out the true rating is measure the loft of the bag with a tape measure. My 0 bag has inches more loft than other 0 degree bags i have seen.

My sleep system is exped downmat 7 ul with a never summer 0 down bag and a fleece liner. The liner is great moisture control, it takes the moisture instead of the bag and is much easier to dry. I use this for all temps down to -50. I sleep in a tent and havent had any problems getting cold. I have spent over 100 nights in the bwca in the winter. Having the right gear makes it much more enjoyable.

I got a -60 degree Feathered Friends Snowy Owl last year and LOVE it :) I get super cold when I sleep so I went overboard with the temperature rating (I've been out in the past at -35 and was freezing).

I've been looking at getting a lower temp rated bag like a -20 or maybe a -40. I know my wife and I would definitely not get cold in those although she complains about the cold in her 0 bag when she is just out in upper 30 temps.

I sleep in a Mountain Hardware "Ghost" Down -40 bag. Love it and have never been cold - opposite problem sometimes before the fire goes all the way out when going to bed. We hit -40 last Feb - so I got to truly test it at its outer range. My buddies in there -20 bags were scrambling to add clothing. :)Also use the Exped down mattress as others have posted as well.

Mine is a -20 F.degrees and a -30 degrees.
The winter bags in my opinion hopefully rate at least 20 degrees colder than when your going. My opinion bags are rated at their degree rating when I would be froze solid.

Yes I have had to sleep fully clothed and even with like a snowmobile suit setup. Usually I am not cold at night down to -30 degrees below. Tent usually is worth like 10 degrees warmer. A wind can make a big difference. Winter you want a wind protected area definitely.

Coldest slept was like -35 degrees F. a few times. The worst was with very strong winds and cold temps-it was survival time all the way.

Good point WRT the exped mat. Getting signficant insulation between yourself and the cold coming up from beneath is key to a good night's sleep.

I have an old -15 slumberjack that works but is in desperate need of an upgrade to a more compact, lighter bag!
