sleeping bag liners

Dang, I've got some nice sleeping bags!! All of them are nylon, and the stuff makes me sweat like crazy. I use an army surplus bag liner (cotton) it barely works. I've seen cotton, silk and fleece liners. I've heard that fleece causes as much sweating because it's made of plastic fibers as well.

There are vapour barrier liners-no doubt designed to keep the sweat out of the sleeping bag but also making you sleep in a pool of your own sweat.

Any suggestions?

Wear poly long johns and tops when sleeping in a bag, i'm the same way and sweat like a hog in those bags but wearing those poly's has stopped me from sweating at night.

M70Nut has the answer - get a quality set of thermals, top and pants, and forget carrying a bag liner.
The New Zealand company, Ice Breaker, make high quality garments from merino wool, but you'd have a wide range of similar brands in North America. Jim

Is merino wool even a bit itchy? I'm very delicate

thanks for the responses

I've never experienced any problems with the Ice Breaker range of merino wool. however, if you are sensitive to woollen clothing, you may as well use any number of the synthetic thermal garments. Jim

Try this.

Unzip the foot of your bag a few inches. This promotes some airflow when your bag might be a little too warm for the weather.

Even if I have the bag zipped up around my shoulders and the hood up, sometimes I still leave the bottom of the bag open a few inches.

Chef, a few years ago we bought a couple Crappy Tire nylon sleeping bags, and some fleece liners. I don't like the liners, as they are static like crazy (maybe in combination with the nylon), and the nylon bags aren't worth sh*t, unless on a warm night (and when do you get one of those in the mountains). If anything I'd go with a flanel liner or some such. It'll add some warmth and absorb all your excess body fluids (in moderation of course) ;-)

I shudder at the thought of wool. I've yet to find the wool garment that doesn't itch.

I have to admit that sweating is not generally my issue. I'm always cold... even when the temperatures are moderate.

flannel all the way, as long as it is light weight. My daughter sews up 2 for me before every trip-- just remember to air it out/dry the used one every morning. If that is not possible, guess what the second one is for?

The old Army silk liners work fine for me, but there are better made ones out there for a few $$$.
Paddy Pallin make a great one.

No, it's not just you. Most of the guys I worked with didn't like the fleece liners for the same reason.

cc, there are different causes for "excessive sweating" in sleeping bags.

The bag has too much insolation for the temperature.

The bag doesn't have enough insulation for the temperature. (I know there will be some "doubters" on this one).

OR.... it's a crappy bag that doesn't "breath" properly.

What temps are you talking about and what kind of bag do you have?

I have 3 bags a really light one- don't know the filling. I also have 2 north face bags, one fiber filled and one down. I've used the light one at -10C and it definatelw was too damned cold for those temps but I still sweated in it. I'm an "insensible" sweater I can sweat any time in any temp. but I don't look wet It's just a light dampness that i can feel. Any time I'm in contact with nylon it's way worse. that's why i've used the flannel cotton liner. I think I might try the poly underwear idea this fall and see how it works.

thanks everyone for the suggestions
