I am trying to get my 25* rated down bag rerated to at least 15*-20*. I have now realized there are several fabrics to line a sleeping bag for more warmth. Is there a difference between the micro fleece and the silk liners to add warmth to a sleeping bag? How do they differ?

They all end up around your feet by morning,unless you can pin them to your bag

I have a fleece liner that I got from LL Bean that works great. It comes up to my neck and usually stays up there for the night. It also has a zipper in it so its great for getting out of too. I would say it adds about 10 degrees to my 20 degree bag. Good Luck.

We swear by our silk liners, purchased from Campmoor. We are not sure if they add the 10 degrees of warmth as advertised. However, they certainly add warmth. They keep the bag cleaner and dryer (which also keeps the bag warmer). They are so easy to wash. In the summer, the nylon of the bag doesn’t touch you, so the bag doesn’t have a clammy feel. The silk liner is about the lightest you can buy. It comes in a very small stuff sack or you can keep it in the sleeping bag when you pack it in the morning. We never had a problem with the liner bunching up or sliding down.

My favorite as a bag liner is the Sea to Summit
Thermolite bag liner. They really do add about 15* to a bag and I never had a problem keeping it in place. It also feels pretty soft and nice without being slick and makes a good hot weather bag on its own (which is nice for 9oz.)

get a warm sleeping bag for winter trips. they can be had for little money. you and your bag will get stinky after a while, but not as stinky as that one beside you, pissing and moaning about how cold they are while you secretly stick a leg out of your bag to be comfortable! i have a 20 year old -25 Wilderness Experience Solo North Country that has seen -18 degrees and huge winds in the GSMNP, and truly savage Mt. Mitchell N.C. where the wind made breathing impossible unless you turned your back to it. that bag with a Goretex bivy sack kept me warm as the arms of your lover next to a fire at the ski resort. please don’t suffer in the back country. stay warm. you might have to save someone! b

I swear by my silk travel sheet! I think silk liners add roughly +8 degrees to a bag. I do have a semi-rectangular bag, though because I can’t stand/sleep in the mummy! It’s also nice to sleep in it on top of the bag in warm weather in addition to keeping your bag clean…better to wash the liner than your down bag. :tongue I did open mine a bit more down the side. If you want the opening on the other side if needed in a hostel, you just turn it inside out.

This certainly increased my knowledge and use of bag liners. Thank all of you very much.

i use a nylon bag liner. pretty much same as silk, just $20 cheaper and about 4 oz. heavier. love it. it definitely added the 10 degrees it said it would.
