Not a vital piece of gear, or one I tend to use much (being honest). But it’s versatile: can be used alone, in the intended form (to sleep in), or even wrapped around an inflatable sleeping pad, to add a few °F of warmth and also some comfort and convenience (to keep sleeping bags and pads cleaner). Sleeping comfort is very subjective and personal. But if the concept of “layers” applied to sleeping system insulation makes sense to you, a sleeping bag liner can be a very effective and versatile… Full review
It does work! The extra few degrees granted by the liner allowed me to take a light sleeping bag on a fall bike packing trip. And it was easier to wash than the sleeping bag after three weeks of use. Quite simple product that just gives you more flexibility on trips. I have not used it in the height of summer as a standalone sleeping bag. The material feels quite nice and, obviously, is an easy thing to wash. I have never used a bag liner before and have found it to be a great addition to my sleeping… Full review
Perfect for traveling and staying in hotel conditions where they use harsh laundry soaps. I purchased this Sea to Summit item on a recent trip to GA to use to give me a barrier to the harsh laundry soaps used in the hotel I was staying in. I have travelled for a couple of years with a larger lightweight sleeping bag, but it was taking up too much space in my one piece of luggage. This was an expensive switch to a newer lighter weight and smaller solution, but one I am happy to say was a perfect… Full review
A ightweight and compact liner that improves insulation and protects the inside of a sleeping bag. Can also be used on its own for really hot muggy nights. I always use a liner as part of my layered sleep system. Foremost, it gives the inside of the bag a degree of protection, especially on longer walks where access to washing facilities is limited. Additionally, it actually does improve the insulating properties of a sleeping bag by a couple of degrees —I really notice the difference with and… Full review
A good stretchy thin liner from Sea to Summit. 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!

Reactor Thermolite sleepong bag liner: Extend the comfort range of your mummy sleeping bag Increase warmth by +8 c (14 f) Regular length 210 cm 6' 11 in Width 35 in Brand New This is my first Sea to Summit sleeping bag liner. I just got it so I can't give you any feedback yet. Wait until the predicted BLIZZARD hits in February (Old Farmers Almanac) at which time I will edit my results. On the label, it says that there are other temperature ranges available. Too late. I have the regular one now and… Full review
This liner did exactly what it is supposed to—it made my summer bag 20 degrees warmer. Worth the purchase. Kept me warm and cozy on cold nights. Thermolite used with cheap 45°F bag seen here. I bought this product to use with my cheap summer sleeping bag so I didn't have to spend a lot of money on a warmer bag. This product worked exactly as it should. It added considerable amount of warmth. There are three different ones and each one adds more warmth. I bought the Thermolite Extreme. It was… Full review
This is a great liner at a much better price point than most. A must to protect and keep your bag clean. Perfect for summer trips, not much help for extra warmth. First things first, I bought this based on a Killer Review on Trailspace. It was super helpful, and there’s no way I could do better, and I agree with all of his points, so definitely check his review out: https://www.trailspace.com/gear/alps-mountaineering/microfiber-mummy-liner/#review34340 My additional thoughts: Entry & Exit:… Full review
Limited warmth, but soft and comfortable to sleep in. I bought this product last winter to help out the warmth in a cheap sleeping bag, which it did slightly. Sea to Summit claims it will improve warmth up to 25 degrees F. I would guess this liner adds maybe 10 degrees of warmth. I'm a big fan of Sea to Summit products in general, some seem a bit gimmicky or overbuilt but everything I've seen is well made, quality stuff. And this liner is no exception. The liner is basically a soft fleece/flannel… Full review
