This is liner is the third one I have had and is superior in every way to the first two. Roomy and the ventilating side panels do make a difference. Will be great for coping with the heat in Israel when I return later this year. With temperatures regularly in the thirties and forties this small easily packed item is an essential. I give it a 15 out ten on the great scale.

I used this on a Tassie trek. It was ultra compact in my pack, comfortable to sleep in without tangling, and added a bit of warmth. Very happy with it.

Light, small and practical. Very comfortable !!!! When I go trekking and cross-country trekking, I carry only this inflatable insulating liner.

Very happy with this sleeping bag liner, not only helps with insulation, will help keep my nice new sleeping bag from getting dirty inside
The liner works extremely well. The stretch aspect of it insurers that you don't get that restricted feeling like you do with some liners when they twist as you move.While the material is light and breathable it's still substantial enough to remain in place rather than shift down in the night to the bottom of your sleeping bad like other brands.I have also used it with a quilt and it works just as good as with a sleeping bag.Not cheap, then again it's sea to summit quality and performance that you are paying for and can rely on.
Fantastic product: lightweight and comfortable. I'm very satisfied with the purchaseIt's not very easy to put it back in the transport back (as usual with this kind of things)
6 nights in this. Plenty of width but not over long and therefore difficult to pull up to cover your head and I'm not very tall. Not really a mummy shape either, tapered at the bottom but no head "cowl", just a square top
Not being a fan of sleeping bag liners I was not expecting much... but I was pleased to find this very comfortable and practical to use. There is plenty of room for your feet in the tapered end and the stretch panels means you can move around and get in and out without ripping the sides. It is light weight and packed away easily. I used it on several hut based hiking trips in NZ and found it was great either in the sleeping bag or to sleep in and use the bag as a doona if it was warm.. I bought it to use with a S2S Latitude II sleeping bag.
This product is great! Very comfortable!
I can recommend the Premium Silk Travel Liner, it is very comfortable to sleep in, both in a sleeping bag and in a cottage bed or so. It is quite warming, so that I actually didn't need anything else covering me while sleeping. The one downside I see is that it doesn't have a hood, so shoulders tend to stick out sometimes, especially if you are a bit taller.
