Sleeping bag liner – help!

Check out the Mountain Laurel Designs Mountain Quilt/Bag liner. 2.8oz, $65.

I can offer no feedback however, as I have never used a bag liner. If you are dealing with really warm summer nights, this one could certainly work in place of a bag/quilt.

I use a Sea to Summit liner. Got it w/ a REI dividend a few years ago.

No complaints, but I don't normally use it in the traditional sense. I tend to use it to go over my quilt and sleeping pad, instead of inside.

Hi,
I've got two liners, both made of silk,that I got on two different trips, the second one bought because I forgot the first at home.The makers of these are unknown although I bought the first in NZ and the second in Italy. I bought these because they were required at most hostels(refugios,hutten) we stayed at.
I tried to integrate them into my backpacking system but they were a pain in the………… to get in and out of. Especially in the middle of the night.
So I keep these for our next trip up to the Dolomites but other than that I find them useless.
I wear my wind pants to sleep in if i'm feeling really dirty.Or rain pants if dry but the wind pants work well as a layer to keep the bag/quilt clean if its not too warm.
I also use a military poncho liner as a bag in the BWCA during the summer. Any surplus store would carry this.
Hope this is of use to you

I recently got a nice 4.85 oz silk liner from spirits_of_vietnam on ebay. It was $13 and took around 20 days to arrive from Vietnam.

Silk liners from 8 momme Habotai silk are fine, but they do have a limited life compared to synthtics.

Cheers

I use a Sea to Summit Reactor Extreme Thermolite — mind you it's 14oz so best reserved for cold conditions. I've seen wildly varying reviews out there but personally I love it. Used with my synthetic LL Bean 5° bag down to -20°F this past winter and I was down to my base layer and super cozy. It really made a difference, plus it's thick enough you can store your water and stuff in-bag without it being a nuisance. Also used with my Ultralamina 15 down to about 20°F and it made a big difference. Not the cheapest or lightest but in cold weather it's on my must-have list!
