Comfortable, good value
Size: 95"x35/22" Color: Natural
I purchased two of these sleeping bag liners and used them during a two-week camping trip this summer through the Rockies. The liners are well-constructed out of a comfortable cotton material. I washed them once before use, and that removed the small amount of stiffness in the fabric. I'm not sure why, but I was a little surprised that the liner didn't have a zipper or other opening. It is formed like a large sock with the opening only at the shoulder area. The liners really helped keep us warm and comfortable during a couple cold nights. The only criticism I have are related to my peculiarities, rather than the product itself. I'm a stomach sleeper who moves around a lot as I sleep, so a couple of times the liner got a little tangled around my feet. Also, it's rather awkward getting into it. I found that if you put it on like you would a giant stocking, it is much easier to manage. Just gather the sides of the liner in both hands and put your feet inside, straightening the liner as you bring it up your body. Of course, you should do this while seated in your sleeping bag! After you have the liner up to your chest, you can zip your bag, and pull the liner over your shoulders, if you wish. Overall, I think this is a good value for a good product. I hope it extends the life of our sleeping bags. We will continue to use the liners and do recommend them. I think people who sleep on their back will have no trouble with the liners. ... show more

Keeps getting softer!
We've bought three of these now and they just keep getting softer with every wash. I've used one of these for more than 200 nights with no sign of wear. And, wear and tear on my sleeping bag is greatly reduced. We replaced a couple of Cocoon silk bag liners with these and are happy we did it. The silk liners didn't hold up well at the seams. ... show more

Mummy Sleeping Bag Sheet great for HOT weather!
Size: 95"x35/22" Color: Natural
We were going on vacation to visit family, my kids would be sleeping in the loft of a cabin in 90+ weather. I bought these so they wouldn't be too hot (their sleeping bags are for winter camping, so TOO hot!). These were perfect! A nice light sheet to be comfortable in on top of their sleeping bags. I sent it with them to Scout Camp also... I hate that the carry sack is so small, it's hard to shove it back in. ... show more

It's very light weight which may or may not be good for campers
Size: 95"x35/22" Color: Natural
Here's the thing, this will work as a sleeping bag liner. But it's fairly thin, and there's not side zipper or entry point. It's very light weight which may or may not be good for campers. Bottom line is it'll work, but it's a little pricey for what you get.

Size: 95"x35/22" Color: Natural
This fit me perfectly-I'm 5'1" and I love to cocoon myself in my sheets/blanket but I don't know it will be big enough for a tall person. I found the fabric light but strong enough so the sides don't tear. It was also perfect in weight under a lb.

You get what you pay for
Not very durable, thin material. Will rip/separate easy.

A little thin, won't help keep you warm, but will keep your sleeping bag clean.

Keeps me pretty warm!
Size: 95"x35/22" Color: Nile
Keeps me pretty warm! :) I didn't realize that "Nile" was a pattern, so be aware that you're not buying a solid teal colored liner. :)
