Kinda cold in my bag

[farmin4u_98948]

I have a Kuiu 0 deg mummy bag. A thermo rest r 5.7 pad.  At 10 deg I had heavy Sitka thermals , hat, gloves, smartwool socks.  And. I was still not comfortable.  Going to wash my bag and see if that helps. I was out 4 days and things were covered in a layer of ice on the outside but I should have been able to get comfortable....   Any ideas ...  thinking of putting a thin closed chill pad under my thermo rest.   I dunno.

I have their 0° superdown bag too, and was cold sleeping in my thermals in a tent at 30°.  Not worth the price tag imo.

This might sound funny but is it possible you were sweaty that caused you to be in comfortable?
The reason I ask is I had a zero degree bag and was uncomfortable because I was sweating and was getting chilled because of that

Try a seatosummit reactor liner it's super lightweight and helps me

I slept In my truck in 28 degrees with a 0 degree bag. I froze my butt off. I need suggestions also

Not all bags are comfortable at their rated temperature limit.   Some do, but many don't meet that limit.  You'll survive at the rated temp but won't necessarily be comfortable.


More insulation underneath is a good idea.  Also a sleeping bag liner is a good idea for adding warmth (also easier to keep the inside of the bag cleaner that way).   


I have a 20F rated Feathered Friends bag.  I will be backpacked into the snow this Friday for 9 days.  Am guessing overnight temps will range from mid 20's down to the teens, and I'll be camped on top of a few feet of packed snow.  I'll have my ultralight cot, a closed cell foam pad, a NeoAir mattress, my sleeping bag, and a liner.  And I have some thick thermal wool top and bottoms as well as down booties if it gets really cold.  And warm beanie hat.   That way I can layer myself to match temperature changes.  The only time in the past that I got really cold was when things got down close to 0F one time...but I have a lightweight packable small down jacket that I can put on in really extreme conditions.


I'd focus on the added insulation layer underneath the bag (adds comfort as well), and the bag liner.

My 10 year old XL-Wide Big Agnus zipper ripped open about 20 inches on 2nd day of my week long hunt last year.
I alway use another down bag between my cot pad and my bag, but you can sure feel those 20 degree nights when you have some serious drafts. Make having to get up in the middle of the night to pee a torture.
I just bought a TETON Sports Celcius XXL to replace the Big Agnes. It would be nice to get 10 years out of this as well.

Bags are rated at survival temp not comfort rating..a zero bag will be good for low 30s Mid 20s for comfort level depending on the person.....if u want to be warm in the cold you need a negative bag..

If u want to warm up a little throw a hot hands in the bag it will increase your comfort level a few degrees...

The easiest and most effective thing for staying warm is to tweak your own body chemistry. Eat as much red meat as possible, you know the meat sweats? That is because it’s incredibly energy dense and your body creates heat when it has an excessive amount of readily burned fuel. Most common backpacking food is the exact opposite of steak, sure it’s light weight but it’s nutritional value is also ultra light. Supplement Iodine and stop drinking fluoridated water. Being healthy keeps you warm, not to say gear isn’t important but start with your body first.

Fill a 1 liter Nalgene with boiling water. Works wonders when we're climbing the volcanos and other big mountains that require overnight on snow or glacier

This is a great trip, but when the heat runs out in the bottle your heat will transfer back the other way so you have to take it out.

Last year in Alaska I was so cold I shivered through the first 2 nights at around 15-20 degrees in a zero degree bag. I started opening the 8 hour hot hands and throwing one in the bag by my feet. It helped quite a bit. I have thought about getting a liner to try with my sleeping bag.

My hunting clothes bag has the best item in it.
A hot water bottle. Fill it with boiling water, throw in your bag down in the bottom couple hours before bed time sleep comfy all night. Never leave home without it. Best 11.00 Ever spent.

I've got a 15* REI bag that has to be at least twenty years old and has about twenty feet of duct tape patches on it. Last February my pad deflated on a 10* night and I basically slept on the ground in a tent with two other dudes. Neither of them got any sleep all night because they were freezing in their 0* bags and sat up listening to me snore. I woke up feeling great.

I'm pretty sure it's more important to find which bag works best for you as opposed to what bag works for others. Find a style your comfortable in, buy a heavier bag if you get cold, and buy the best quality you can afford.

I tired something new this year, put a military wool blanket on my cot then then my pad then another military blanket with bag on that.

It helped quite a bit.👍

I'm pretty sure wool is the answer for everything.
