MYCARBON Travel Sleeping Bag Liner, 100% Cotton Durable and Super Soft 220 x 90 cm Roomy Travel Sheet Portable Lightweight for Camping Bed Bag, Hostels, Coaches, Picnic, Trains with Pillow PocketsGlobal Recycled StandardGlobal Recycled StandardGlobal Recycled Standard

I've ordered 6 sleeping bag liners in total from Amazon of which 4 have been dimensionally "not as described" or had other fitness for purpose issues resulting in them being returned. This item is good quality, generously sized and definitely cotton. It has a really clever design feature which others could incorporate at almost no cost but didn't understand or care enough to do. The top flap is equally open on both sides closed by snaps. This has a number of advantages. Firstly easy to get in and out. Secondly easy to use with either left or right hand zip sleeping bags. Thirdly the fold back flap automatically adjusts for pillow size. At the end of the opening triangular gussets protect against stress at the closure. The material quality makes it a little heavier than some so might be less suited to backpacking than lighter polyester bags. This item is slightly more expensive than some, particularly those featuring 100% polyester, but IMHO cotton is worth the extra cost.

Used for sleeps during care work. Ideal as a sheet to sleep in. Nice soft material, washes well and comfortable. Easy to get in/out with the half opening. Agree with others, not great for pillow as doesnt really fit a standard pillow and does not secure it - hence 4 stars.

very soft fabric, very decent size, well made, the " leg opening" is a great asset , haven't focused on a " pillowcase" yet ( i just put the pillow on top of it out of laziness :) but I suppose it's very handy, great product anyways, I'm delighted with it

It was despatched promptly and the quality was as advertised. Good value

Found this a very useful product and very comfortable. Gave me a good sense of security when unsure about beds and/or pillows when traveling.

Ripped along edging seam after only a couple of uses. Returned for a refund.

I bought this because I was looking for something nice and thin for a camping trip in the height of summer when it was too hot for a sleeping bag, but since then it's proved itself invaluable regardless of the weather.It keeps your pillow in place which is really helpful if you're sleeping on a thin mat. It also works really well in colder temperatures as an outer for your sleeping bag.

Of course it was the wife who suggested wisely that a liner be used as well as the sleeping-bag in the cold nights of winter. This way there is an extra and comfortable layer that can be washed between the dry-cleaning events of the sleeping-bag.The only fly in this acceptable ointment are the poppers along the side of the liner. These poppers pop open most of the time. The solution is probably in my hands: to glue the poppers shut. I will try this.
