To all the backpackers must have.
- Familiarity: I've used it once or twice and have initial impressions
It was cold! my bag was not rated for this kind of cold. Slid into my Sea to Summit Reactor Thermolite extreme bag liner. Became much warmer, and in turn slept much better than the other guys hanging in their hammocks!
It really makes a difference!
- Familiarity: I've used it several times
We purchased this for Ashley because she tends to get cold in the early morning while winter camping.
At first I was very apprehensive that this very thin polyester liner would make much of a difference.
So we paired this liner up with her down sleeping bag & she was warm & cozy all night. We camped a week before in the same conditions/temperature & there was a noticeable difference!
Truthfully claiming a 25 degree increase is a little stretched in my opinion we would rate it 15 degree+, witch I would take any day!
Plus, it has kind of a silky feel... VERY comfortable.
I'm happy to own this Thermolite Reactor sleeping bag liner. It's surprisingly warm, and served me well by itself while sleeping at friends' houses while traveling with just a day-pack. I can't compare the additional warmth it provided while out hammock camping, but it undoubtedly helped.
It's sewn all the way up the sides, which is warm, but when combined with a mummy bag in a hammock - getting into this liner can be difficult! I found the best way was to pull the liner over your entire body first, before entering sleeping bag. Just sitting up in the hammock with feet dangling, then pulling the liner up like a pair of pants and then all the way up over the shoulders. Finally, rotating into hammock and sliding feet down into the sleeping bag.
Better than expected, really.
I didn't expect to really go for the bag-liner idea in general. But I got this liner on sale and now realize that its a great investment.
On one cold hammock-bivvy night I used this liner and the temp difference from inside the liner to outside the liner (but still in my 30degree bag) was noticeable. So it unquestionably makes a difference! I'd rate it as +15 degrees IMHO.
Otherwise, the material is very comfortable (mmm silky smooth, lots of stretch), seems durable, I've washed it once and it felted a little but not anything that affects performance.
The shape is nice, and I like that it has some extra material and isn't completely minimalistic.
I look forward to using it by itself in my hammock on warm nights.
I used this in combination with my 30 degree montbell bag in 20ish degree weather. Granted that's only 10 degrees, I stayed toasty the entire night! At one point I even have to put my feet outside of my bag because they were too hot. Even when my feet were outside the bag and still inside the liner, they still stayed warm for at least an hour before I had to put them back.
If you use this in combination with cold-weather camping techniques, it can add quite a bit of warmth to your bag. I highly recommend.
I used this sleeping bag liner in a 30 deg. bag in 15 deg. weather. It definitely adds a noticeable amount of warmth but not 25 deg. For the weight and packability I was satisfied with the amount of extra warmth it provided. I just left it inside my sleeping bag when I rolled it up and was still about to fit the whole thing in the stuff sack.
Good but not great
On the packaging it says it adds up to 25 degrees to your sleeping bag but i wouldn't recommend it for more then 10 degrees. It is extremely light weight at only 14 oz. It fits well into both my -30 and my 20 degree sleeping bags and doesn't add very much size at all to the stuff sac. I would say its better for summer camping to use on those nights where its chilly but not cold enough for a bag.
Like a sheet in your bag
I like this liner although its not a 25deg increase to your bag's rating, feels more like 10-15. It has a nice feel & is comfortable alone on hot summer nights or in combo w 40deg bag. Price is a bit steep @ $65
Doesn't add 25 degrees
I really hate being cold so got this liner to add warmth to my 30 degree bag. If It added 5 degrees warmth I would be surprised. Will be good at keeping the bag clean, and maybe okay on a warm Florida summer night when a bag is just too warm. Otherwise I found this useless for it's stated purpose.
It does fit nicely in the bag and doesn't restrict my movement.

I am hiking in mid-northern Spain (on the Camino near Santiago) in early June. I do not want to take a sleeping bag and a liner. Is this Thermolite bag liner good enough to take by itself. Does it have a zipper all around it? (Thinking about bed bugs, too. )
In terms of knowing if this will be warm enough as a stand alone product for you, really only you'd be able to know through some trial and error. Some things to keep in mind:
-Night time temperatures in Spain?
-How does your body regulate heat while sleeping?
-What other layers will you be wearing to bed?
-Are you hammocking or sleeping on the ground?
-Are you in a shelter?
If you are hot blooded and the nights are warm and you're on the ground, then this could work great. But if one of those three things is a no for you, then I'd be incredibly hesitant and recommend trying it out before your trip.
At the top of the liner their is a draw cord for synching it tight around the head. The zipper is a left handed zipper that runs from the shoulder to mid shin.
Hope this helps!

On the Camino, you will probably be sleeping indoors, albeit not always with heating systems. A room full of bodies can get pretty warm. This product should suffice in June. You will probably want to take a light base layer -- long bottoms and top -- to wear either day or night if you are the cold type (I am!). Something like Patagonia Silk weight or Icebreaker 150 (my preference). Note: you will probably want to sleep in at least boxers and a tank as you don't have much privacy in the pilgrims' lodgings. It will most likely range from pleasant to unbearably hot most days and nights. However, it can get quite cool.
I will be hiking the Camino in Spain next June. Did you go with this liner? If so, was it enough! Thanks! Hope you had a great experience on the Camino

I have a Western Mountaineering 35 degree bag. Would you trust this liner with that bag climbing Baker and Rainier in the early summer and camping in the cascades in early spring?
Matai, I don't think it would be warm enough for most people as they seem to go for at least a 10 degree bag. Of course everyone is different, add a good pad and sleep in your down and you might be ok but I wouldn't want to chance it. I don't believe the 25 degree rating they claim but that is only my opinion.
