When temps get low, this
[This review was collected as part of a promotion.] When temps get low, this liner is great to take the edge off of the cold air. Comfortable fabric. I am pleased with the results. Partner to a zero degree bag, it is exactly what I was looking for

Perfect Liner!
[This review was collected as part of a promotion.] This liner is always with me, if I am not using to stay extra toasty in my bag, I use it as a pad sheet for sleeping on during the hot desert nights. Absolute must have for any serious outdoors person

reactor extreme really warms up the sleeping bag.
[This review was collected as part of a promotion.] Just went on a 3 days camping trip using my traverse IIv -4 sleeping bag and this liner inside. I am always cold, but this liner really warmed up the bag and made it toasty. Waking up to -3 celsius in the morning, I didn't want to get up because it was so nice inside my bag, liner and tent. For me, I will get down booties though as my feet are never warm. Highly recommended and it is light and packs small.

Enhance your sleeping system
[This review was collected as part of a promotion.] Reactor sleeping bag liners are a must have, not only to protect the sleeping bag but to give added comfort and warmth. The reactor extreme really delivers and its design features, with the arm holes and base draw cord, make it functionally versatile and adaptable over a range of temperatures.

Toasty and feet accessible
[This review was collected as part of a promotion.] Staying toasty on cold nights is critical for a good night sleep for me. The opening at the bottom allows me to have my feet out and still benefit from the extra warmth.

Perfect for “backcountry” campers!!
[This review was collected as part of a promotion.] The insulation on this is top tier, this will definitely work when we go camping “off season”. It packs back up easily, and doesn’t take up a lot of room. It’s soft, and large enough to fit my brother in law who is 6’3 comfortably.
