Great Liner

Used the liner only once, in temps of upper 30s. The drawstring foot enclosure, hood, and arm holes are fantastic. Arms through the holes for maneuverability, or tuck your arms in for maximum warmth. Noticably warmer inside my 30 degree quilt. I will be ordering another, in the warmer version for more versatilty.

My Son And I Both

My son and I both like this sleeping bag liner. He looks like a banana and I look like a spaghetti squash, but despite our size differences, we both fit comfortably in it. It has a gentle warmth when wearing it around camp and the arm free feature is a real winner. It is nice to get in and out of the sleeping bag without having to fuss with the liner getting all messed up - I was always fighting with my other one. I only gave it 4 stars because the hood is a joke. It is so shallow. It does have a draw string, but that doesn't do much except possibly when you are laying down. It would be very cool to have a deeper hood, especially for holding up the back when you are getting into the liner and getting it snapped. The other thing that would be nice is if there was a bit more room when you have your feet out to walk. It makes you take pretty small steps. One other thing I would add would be another snap or two that would hold the length up for when you are walking around camp, as it is, you have to hold it. However, it is still way better than any other liner I have used - the wearing part is genius!

Toasty

Liner worked very well along with 25 degree quilt to keep me nice and warm during upper 20's temps. I really liked the fact you can "wear" this so you don't get tangled in while rolling over at night.

Worth It

My quilt is only comfortable down to about 40°, but with this I’m good down to freezing. Saved me from having to buy a warmer quilt.

Very Nice Liner

This liner kept me warmer than usual on a 20 degree night out in my 30 degree bag. And my bag was clean after 4 days out. Just had to toss this tiny liner in the wash. Put it in a sink with a dash of liquid soap. Then hang it dry. Very easy.

Sleeping Bag Insulator

Bought this for my upcoming Kilimanjaro trip. Seems very warm and should pair well with my 15 degree REI sleeping bag

Simply Awesome

Soft, warm, versatile. . . that's what makes the Reactor so unique. Having the ability to actually wear it around the campsite makes it really versatile. It being super soft makes it comfortable to be in. And finally, it's warm. . . it really works by raising your ability to comfortably handle temperatures around 10 degrees colder than your sleep system is designed to do.

Lightweight Warmth

I purchased all three sleeping bag liners for my RV and camp gear setup. We recently camped and forgot to check the weather. It was much cooler than we anticipated and our liners were our go to warming clothes since we had none. I particularly love the toggle for your feet and the snaps to keep it on your upper body and the hood. We use these in our camper, at the camp, and originally purchased for back country camping and its compact nature. Highly recommend all weights. Great product.

I like this one with the hood better than the un-hooded.

Not For Me But My Husband Likes His

I was hesitant to leave this review but honest reviews are important and everyone sleeps differently. | did not like sleeping in the liner, I found because it was polyester I sweat and was uncomfortable. I was hopeful because my husband has the warmer Reactor liner and uses it in the colder months and likes it. I had to move to a merino wool liner.

Bag Liner

Used this liner at 20k and it was that little bit of extra I wanted. Not much extra weight for a lot of extra warmth.

Very Nice

Packaging is a breeze and easy to. It’s seamless to set up and unpack and get situated I can’t tell much on the warmth as it didn’t fit the situation for insulation but I believe great temperature control .

Super Cozy And Great For All Heights!

I love the material of this sleeping bag! It provides the perfect amount of warmth without getting too hot especially with living in the south. I also love that it is big enough light to fit people of all heights up to 6’6”.
