I bought this liner for a month-long trip to Nepal. The main thing to say is that it is too short and I would also say not wide enough. The dimensions are 2x0.8m and it states that this is comfy for people up to 6ft tall. I'm 5.4ft tall and if I lay flat I had to stick my feet into the bottom corners and still the top of the liner barely came up to my shoulders. There needs to be more material to properly cover over the top of bed linen provided by hostels etc.
There is a useful pillow holder that keeps the pillow from touching you but again this wasn't very big but it did hold the flatter pillows ok.
The material is now looking 'stretched' but is is still kept together. It is also frayed and I have only washed it once on an easy care washing setting. However, the material is quite comfortable against your skin.
This item was cheap so if that's what you're looking for this will do the job.
