Can anybody recommend a travel liner? With this I mean the ones used for hostels and hotels for added security in questionable bedding. I ordered one but is 100% cotton and it’s a little bit bulky, Im thinking about getting one with 100% silk but Im not sure if is worth the cost (usually $50+).

I think the silk is best for traveling. You can find them in various mail order catelogs like Magellen or Travel Smith.

I second silk.

We bought ours at REI. It folds into its own small stuff sack and only weighs 6 or 7 ozs. It's one of those things I don't mind taking because it is so small and light. Adds a layer of warmth if necessary, or can be used as a light cover if the room is too warm for the provided duvet/quilt.

I take a silk Dreamsack - www.dreamsack.com/store/home.php?cat=2 - although I usually only use it for night trains.

We're planning to get them before our next trip. We usually stay in more budget hotels. Usually the sheets are fine, but sometimes the sheets are pilled, and it drives me crazy. So I think a silk sleep sac will be useful.

I love my Cocoon (silk). It is just like the dreamsac, but cost much less ($39.97). The size is nice also. I tend move quite a bit in my sleep and never had a problem. It also comes in a little stuff sack.

Yes I saw that cocoon but was wondering if it really folds into a small package.

I was able to fold it back into the little bag it came with. Which is quite an amazing act once you see how small the bag is. I love it, actually bought 3 DH and DD got one too.

If I were going to pack one, it would be silk. They are lighter and less bulky than a cotton liner so won't take up as much space in your bag.

Having said that. I won't pack a bed liner again. The last time I packed one I never needed it. Every hostel I stayed in had free linens, including hostels in Netherlands, Germany, Austria and Italy. It has become common for hostels to include bedding, the bed-liner is just a waste of packing space.

A word on bed bugs. They are becoming more common in Europe lately in hostels and hotels. Using a bed liner may spread them and many hotels and hostels don't allow you to use your own linens or sleeping bag. Wherever you stay for the night, don't put your bag on the floor. This allows the bed bugs to hitch a ride to your next lodging.
