OSAGE RIVERSleeping Bag Liner, Microfiber Fleece Travel Sheet Sleep Sack for Camping Travel Backpacking, Lightweight Zippered Sleeping Bag Inner Liner, Adults & Kids

These are great as a sleeping bag liner, a perfect ultralight solution to amping up the warmth factor and keeping your bag clean. They are also great to slide between your sheet and bedspread for a super lightweight alternative to heavy blankets. I've bought 4 of these over the last few years, and they are simply wonderful. Great quality.

Light weight and warm. Use it independently for light warmth, unzipped as a throw blanket, or inside a sleeping bag for added warmth. Soft and sturdy construction. Rolled up makes a nice pillow. Highly recommend. I was glad to have it when night temps dropped below 40.

Liner is nice and soft and provides some warmth. The only complaint is that it slides around a lot within my sleeping bag. Not sure what design would be able to avoid this, but because it slides around I end up a bit tangled by the morning.I haven’t used the zippers much and I haven’t had to clean it yet. I’m sure by the end of my field work season I will have an update.

We have 3 of these already, but need one more for this trip. I've been so happy with the first three we got, there was no reason to not come back and get another of the same blanket. These work great to put inside your sleeping bag to add about 10 degrees F more comfort to what your bag is rated. They are also great for the times when it's too warm to be in a full on sleeping bag and you can just use this blanket. Unzip it and you can toss it on your shoulders to keep you warm around the camp fire on a cold night. The whole thing rolls up into a storage bag so it's easy to keep clean and put away.

This is nice warm substitute for the usual blankets.

I took this product on a winter campout in Alaska. The temperature was forecast to be between 0-10 degrees F. My sleeping bag is only rated down to about 20F. So I was hoping to bridge the temperature gap with this. It did seem to do the trick. It felt nicer than my sleeping bag and kept me a little warmer. However this product when packaged for a backpacking trip was bigger than what my sleeping bag stuffed down to and was maybe a little less than twice the weight of my sleeping bag.

Very soft, warm & breathable- perfect for the cool, humid nights in the mountains of Costa Rica. I bought 2 & have them zipped together to make a double size & use it on my bed

I bought this in anticipation for an upcoming camping trip. Sleeping bags are notoriously difficult to clean and many sources online suggest getting a sleeping bag liner such as this one to act as the flat sheet that goes between you and your sleeping bag. This is extremely lightweight and can be folded down to be very compact, along with its own storage bag. I found it to provide some warmth and acts like a light blanket, except it also has zippers on 2 sides so you can zip yourself up! This is very easy to clean and very comfortable to sleep in. And if you get really too warm at night, you can always unzip the sleeping bag fully to act as a mattress and use this as a light blanket! Very useful both on camping trip and/or for at home! For those wishing to live "small" and downsize but still want a multipurpose blanket for the couch/lounger, I would highly recommend this!
