Sleeping Bag Liners?!?!

Well im getting ready for a solo winter 2 night hike. I have looked at making a sleeping bag liner but dont know which type to make. My sleeping bag is a light bag i think 40degree bag. Wandering if a liner will be worth making and the best way to go about it??

For two nights forget a liner. Your bag will stay dry enough.

In winter, on one week or longer trips, the only type of liner I'd carry is a waterproof, aluminized ripstop liner to keep perspiration from gradually wetting my bag insulation day after day. I got my material from Seattle Fabrics. Or you can buy one for $75. to $100. !!

In spring and fall I use my fantastic WM Megalite down bag & very light polyester long johns to help keep the bag clean, not really for warmth.

You didn't mention your location. A 40-degree bag isn't even warm enough for summer in many locations.

im in ohio but plan on camping in WV the trip is in about a month.

I have a fleece sleeping bag I just use as a liner. I don't know about where you live, but for some reason fleece sleeping bags are everywhere in Washington. Cheap too 5$ so I don't bother making any.


You want to make the liner to keep you warmer correct? I sleep in a hammock in the winter and since I use a very bad sleeping bag (it's rated to zero, but really it's bad in 40!) I have to get creative and bring a whole lot of insulation. I would guess you don't sleep in a hammock so you probably won't need to bring as much as me, but here's what I do:

I use a crappy bag (lets say it's a 45 degree bag)
Fleece liner (adds about 10 degrees)
Self-inflating pad
CCF pad for my shoulders
Wear all my winter clothes

It takes all that for me to stay comfortable and warm at 15degrees with a few knots of wind.

Again, I'm in a hammock so my example is different. If you don't want to buy a new sleeping bag it takes a lot of extra pieces of insulation to stay warm.


I didn't really answer your question, but it's fun too share <img src="/forums/images/graemlins/smile.gif" alt="" />

If you go the liner route, I would suggest making a trial run at your house first. I am just clausterphobic enough that when I added a liner to the inside of my bag, I couldn't stand the closeness. So what do I do for snow camping? I take an extra down sleeping bag (unzipped all the way) and use it as a comforter OVER my regular bag. Of course, you gotta have the room in your backpack and be willing to carry the extra weight but most snow hikes that I have been on are pretty short. With my Troop, we just basically have the boys hike over the hill from the parking lot and call it good. (One time, the Leader had the boys start at the parking lot, hike over and around the hill and then back to camp next to the parking lot. He thought it was great fun (the other adults weren't laughing))

Old Scout, et all

I carry a large winter coat that works as a comforter over my torso. I put it around my back and tuck it under behind my kidneys. <img src="/forums/images/graemlins/grin.gif" alt="" />

I might suggest wearing warmer clothes in the bag to extend its range. Bibs are way cool in the Winter.

It depends on what you are going to use the liner for. If you are using it to add warmth then there are other options to a liner. If you are using it keep sweat, dirt and so forth off of your bag then I would recommend something light like a silk one made by Jagbags.

In warmer weather I use a silk Jagbags liner. It is a mummy shape and weighs right at 5 oz. If I am going to be in colder weather where I can wear my clothing inside my bag then I don't use the liner.

Boy, can I ever agree with that! I've squeezed through Nohoch Nah Chich and was not as claustrophobic as I get with a bag liner that gets all twisted up around me in my mummy bag. Add to that the cocoon effect of my jungle hammock and I have been known to get out and sleep on top of my sleeping bag on the ground. I've begun using my bag without a liner and hand wash it in a river if needed. Brum

One of my friends has a jungle. I used to call it a cocoon hammock ah ha ha ha.
You can almost spread your arms out all the way in a Hennessy.

I tried using one of those silk liners in hopes of bringing a 30 degree bag (Marmot Hydrogen, excellent bag) down a few degrees more. At least for me, it didn't work--I'm a cold sleeper. Plus, by morning I was so tangled up in the liner that it took me a couple of minutes to get out of my sleeping bag!

Unless your bag fits quite loosely, putting a fleece liner inside may be enough to compress the insulation at your wide points. That will make the bag colder than if you didn't have the liner!

Yes, I researched the Hennessey Hammock and the Clark Jungle Hammock before buying the Clark. I made my decision based upon knowledgable user's reviews related to quality of design and materials and the number of people currently moving up to the Clark from the Hennessey. I don't care for the Hennessey's bottom-only Velcro entrance, or that you can't remove the mosquito netting to sleep (or lounge during the day) open air when bugs are not a problem. I'm very pleased with the Clark. I put mine through its paces in Mexican jungles often. The cocoon effect only happens when I'm in a mummy bag, and is mostly due to my wide shoulders. Brum

Try using the little imocons available here. They tend to better express your emotions. <img src="/forums/images/graemlins/smirk.gif" alt="" />

Ah Ha! So it DID bring your temp rating down a bit OM...well, it did in the morning while you wrere wrestling your way out of your bag you got all hot n' bothered <img src="/forums/images/graemlins/smirk.gif" alt="" />
