### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great for backpacking and gives you a little extra warmth
  

*by F***2 on Reviewed in the United States on October 8, 2014*

Very light weight and warm.  Great for backpacking and gives you a little extra warmth.  Not sure it increased the warmth of your bag by 20 degrees though.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Too thin as a isolation from hotel bed

1. ❤️❤️❤️❤️❤️Delivery; I'm really impressed, with how the Summit Reactor Insulated Sleeping Bag Liner was delivered. It arrived one day after I placed the order and everything was in condition.2. ❤️❤️❤️❤️🤍 Quality; The craftsmanship of this product is truly impressive. The fabric feels incredibly soft with a silky and cool texture. The liner as a whole is impressively lightweight and compact making it super easy to pack and unpack. However, I do have a concern when it comes to the fabric thickness for my use, which is protecting my skin from hotel beds. Even if I were to use it for camping or other purposes I still think it's a bit too thin for sleep.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    well, its lightweight.
  

*by A***N on Reviewed in the United States on September 19, 2021*

I purchased this from my local camp store in hopes of raising the comfort rating of my warm weather sleeping bag (45 degree marmot sleeping bag) and I thought I could get this to just add some warmth for an upcoming backpacking trip where Temps will be in the 40s.Well, I tested this liner last night since the Temps dipped below 50. I did sleep in only my underwear trying to really test out the warmth, well I was pretty cold. I almost always sleep with my bag unzipped except last night I zipped it up after laying there for a couple hours and even pulled the hood over my head and was still cold. By 4am I was putting on insulated tights and some wool socks (which I had taken with me just in case I did get cold) this liner definitely does NOT provide the advertised warmth rating , it might increase your sleeping bag by 3° , certainly not 11.Now on to the rest of my sleep set up so people can see what else this liner was paired with. I had my Klymit insulated static V sleep pad with insulated V quilt, sea to summit aeros premium pillow, marmot nano 45 and this S2S reactor compact plus (didn't realize it was compact until I got it, luckily I'm short or it wouldn't work. I'm 5'8 and its barely long enough to get the hood over my head) so my sleep system was all cold weather rated except for my sleeping bag.Honestly the only thing I see this liner being good for at all - is helping keep the inside of your sleeping bag / quilt clean
