Light weight and comfortable to sleep in. Checks all the boxes.
The widest size allows for freedom of movement (you can toss around at night and not end up wrapped up like a mummy). Super light weight, didn't even notice I had it in the pack

Great material
This thing is super comfy. It feels great on my skin. I haven’t had the chance to sleep in it camping yet but I did sleep in it one night to test it out and it was great Edit: slept in it on a backpacking trip and my opinion is the same, it's great. I mean, it is a sheet but sewn into a bag. You know what that is. It packs down small and will definitely be on every camping trip now

Good for travel
Light, comfortable, and easy to wash. Great option for travel, especially when you don't want to sleep on the hotel sheets. Can be a little difficult to get in and out of.

Small but exactly what I wanted.
I really like this bag but it is definitely not big. I wear a medium size t shirt and I’m telling you, if you wear a an xl, you will probably not fit in this bag. I had just enough room to fit my arms in next to my torso and I don’t know if I could if I was a size bigger. I essentially use it for tent camping on a hot night when I’m concerned about bugs possibly getting past my tent mosquito netting. It could be more breathable but it’s as lightweight as possible and takes up hardly any space. It’s definitely cool and comfortable. I like it not having a zipper because I don’t want to feel it. I didn’t rip it apart thrashing around trying to sleep so it seems durable.

Great sheet/cover for a sleeping pad!
First off, I bought this as a sleeping pad "sheet" to use with a camping quilt. My idea was to put my sleeping pad inside of this liner and then use a down quilt instead of a sleeping bag. This worked great! I already have a high-end (expensive) "sleep system" quilt/sheet combo for colder weather, but it's relatively heavy and a bit too hot for warm weather camping. I had basic lightweight quilt for warm weather, but still wanted a sheet to cover my sleeping pad. I was hoping this would fit over my pad (25"x78"), and it does, nearly perfectly. Now I have a lightweight sleeping kit that is less than half the weight of my cold weather kit, and for a small fraction of price (making it worth having two kits). I assume this works fine as a liner, but for my intended purpose, I can highly recommend this liner/sheet.

Light as soft
So nice and lightweight. Made my camping trip so much better. Felt cool to touch. Also soft. It wicked my sweat off the sleeping bag so things felt so nice even after 4 days of no showering. Love it.

Works beautifully

Larger opening needed
I liked the feel of the fabric. I wish it had a 2-way zipper. I like the option to have my feet out from under covers.

I used the Frelaxy ultralight sleeping bag liner on a canoe camping trip during fall and winter months. It saved me as the night got freezing and I needed more warmth. Honestly if i did not have it i could've froze to death!It packs very small and adds a clean layer inside the sleeping bag. The fabric feels smooth and dries fast. It gave me the extra warmth I needed and without it I could have been in serious trouble with it. A solid choice for cold backcountry trips.

Très bonne doublure de sac de couchage : ultralégère, compacte, et vraiment agréable au contact de la peau. Le tissu est doux “style soie”, respirant, et donne une sensation plus propre et plus confortable en voyage, refuge ou camping. Par contre, j'aurais aimé un tissu un peu plus extensible

I use this to protect my inflatable from my dogs nails, super lightweight and small, perfect for backpacking

Very comfortable and adds a surprising amount of insulation to your outdoor resting experience.
