A good stretchy thin liner from Sea to Summit.

  • Expensive
  • Not available in mummy style

I bought this liner two years ago and have used it on several occasions.


The Adaptor Traveller differentiates from the Adaptor model by a pillowcase that comes in handy when unsure about a pillow other than yours. Therefore possibly a little heavier too. Mine was 305gr with its carrying bag.
It features a very thin stretchy Coolmax fabric that won't give up on a restless sleep due to its elasticity. So no tears when you wake up.

It is comfortable! Like sleeping in cotton comfortable! And breathable and wicking (Coolmax delivers) so you don't get that sticky feeling in the summer season.

But it does not fully cover a standard size pillow. That's an issue...


Also the Traveller model doesn't come in mummy style option for the weight conscious if let's say you have a mummy sleeping bag so you don't have use of that extra feet room that this liner offers.

Also pricy compared to the Cotton model which, at that time, cost 21 euros.

Nevertheless I am very happy with it.
