To Line Or Not?

Why didn’t you say so?
The Woobie rocks!
You still need decent ground insulation, warm hat, gloves and socks.
Good luck!

I LOVE, LOVE, LOVE, my liner.
It makes my bag warmer - when I need it.
It keeps my bag cleaner - and if I am out too long, I can wash the liner to clean my "sheets."
It provides something to sleep in when it is warmer, and I don't want my bag over me.
It allows me to feel more "normal" when sleeping as I don't have to feel the slippery nylon of my sleeping bag

I usually use a liner; not so much to stay warm, more to reduce the frequency of bag washes. That being said, I usually make my own silk liners. It is difficult tot find an off the shelf liner that will fit a different manufacture’s bag.

Thanks everyone for your thoughts! Looks like I just need to dress warmer and or keep my poncho liner in my pack if it gets too cold. I was wanting to get rid of the army poncho liner (light weigh quilt) by switching to a bag liner. Witch would save some weight and space.

i use my poncho plus poncho liners as over/under quilt if the temp is going to be less than my 23* bag. I use the to nap at home, my wife calls them my security blanket.

I keep going back and forth on getting a liner, not so much the warmth but the clean factor. I sleep in base layers so that helps with the warmth. I have gift cards burning a hole in my pocket so that’s a factor in the decision.

That Sea to Summit liner is a waste of money.

I just got my new sleeping bags (down 15deg.). In testing I found them fine down to about 25deg...

Stop, before going down the liner rabbit hole. Explain this! WHY? Under what set up? What brand and model 15* down bags? How old are those bags? What do you mean by new?
