Most summer campers!- this is all the sleeping bag you need!
Super cozy liner or as sole bag on 56'F nights or warmer! Wool is the ultimate comfortable material when wet or just while living in extended high humidity/ low to moderate temperature environments. I had/have a silk liner from cocoon to protect my expensive down bag and was impressed- so I got this "liner" to extend my bags warmth. Wow! most Summer campers could just use this as their primary sleeping bag and be fine! Treat all wool with respect-it is/was living hair!!!-I use human shampoo then conditioner on wools if I handwash; or the super fantastic Koomburora wool/silk wash if I front load delicate cycle wash. Follow up- used it during a rained all week bicycle tour late Sept/early Oct and found it comfy every night!

Merino Wool is the Best!
I got this for my emergency back pack. I used it on my bed the first night to try it out. It was very warm. I intend to use it inside my sleeping bag because my sleeping bag is so silky it would be uncomfortable and make me sweat. It should keep my down sleeping bag from needing to be cleaned. It is easy to wash and dry, Merino wool is the Best!

Great warm liner for cold nights
I love this liner. It is so soft and comfortable. It has plenty of room, even for a larger person like myself. I bought a down sleeping bag recently, rated for 18 degrees. Camping in the mountains this summer I found I was still cold, even when using my sleeping bag in conjunction with a silk sheet liner. With the addition of this wool liner I am toasty and warm all night and I love how small the liner packs down.

Very comfortable and nice. Worth the money
Awesome liner. Worth the money, helps a little with added warmth but keeps your body from sticking to sleeping bag. Very comfortable and keeps you from stinking up your down bag.

Highly recommend
I love this! While it's not super thick, it adds quite a bit of warmth to my sleeping bag, and allows me to launder just this liner instead of my feather sleeping bag. Well-made, light-weight, and cozy.

Nice Liners
I really like these liners!! they're one of the best I've used, I liked them enough to buy 6 of them for family members. on cool nights this is good by itself to keep me comfortable. and they're super soft also.

One Star
Terrible and expensive. Did not provide any additional warmth. I returned it.
