Kept me pretty warm with my 32F down sleeping bag in 25F weather. My feet got a little cold but wasn’t bad enough to keep me up all night. Read more

Great liner for summer months
i’m not keeping this because I need something a little warmer. I’m getting ready to start the Appalachian Trail and I just don’t think this is warm enough for me looking for a warmer insulated liner for my sleeping bag. If I wouldn’t be hiking in the cold, I probably would’ve kept it. Read more
It worked for me!
First night was in the 20’s f and worked great with my sleep system. I woke up to a small amount of snow and was warm without feeling drafts in my hammock. I use this every time in my sleep system Read more
Works great
Works great. My bag went from adequate to comfortable, with minimal weight added to my pack. Read more
Sleeping bag liner.
This bag liner is nice and warm. Drawstring bottom is great for sitting around the fire and keeping your legs warm. The snaps and hood helps keeps wrapped around you while you roll around at night. Was out for a cold evening and usually sleep in my puffy. Ended up taking it off in the middle of the night cause the liner was keeping me extra warm. Read more
Very warm, easy to get in and out of
I used this for several nights in 30 degree temps as a liner in my hammock, combined with a 20 degree top and under quilt. With just the 20 degree quilts I would have been way too cold with the wind chill. However this liner provided more than enough extra insulation for the conditions. Also, the easy close foot box made it very convenient to get in and out of, especially with the added difficulty of hammock camping. Read more
Versatile and effective both as a warmth-increasing line and as a standalone bag
I bought this to store in my camper as a 'just in case' item or spare, and have been very pleased with it. It definitely adds warmth to a main sleeping bag without making one feel clammy inside, and it works nicely as a light bag on warmer nights. The open footbox adds further versatility (you can close it with a drawstring for maximum warmth) too. If you're through-hiking the AT, it's too bulky and heavy to justify taking along, but if you do RV camping or are going out for one or two nights and expect variable weather, this is a very worthwhile addition to your kit.
