    Very nice liner

    8 days ago
    [This review was collected as part of a promotion.] 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.

    [This review was collected as part of a promotion.] Bought this for my upcoming Kilimanjaro trip. Seems very warm and should pair well with my 15 degree REI sleeping bag

    [This review was collected as part of a promotion.] 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.

    [This review was collected as part of a promotion.] 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.

    [This review was collected as part of a promotion.] 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.

    [This review was collected as part of a promotion.] 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 .
