    [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

    [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.

    11 months ago
    [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

    a year ago
    [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.
