The THERMOLITE® Reactor™ Compact sleeping bag liner is the ideal choice for gram counters under 6 feet who want to add warmth to their sleep system. The world’s first ‘hybrid’ sleeping bag liner uses a combination of two weights of THERMOLITE® fabric, with the warmer fabric strategically positioned across the torso and in the footbox. The hollow core THERMOLITE® fibres work like the hollow fur of a polar bear to trap extra insulating air. The Reactor Compact Plus keeps your sleeping bag clean and is super easy to wash. It will bump up the warmth of your sleeping bag considerably, depending on your metabolism, your sleeping bag and sleeping pad, and the environment.

FAQs Is it suitable for use with a rectangular / wide sleeping bag? The knitted fabric of the Reactor is so stretchy that you won’t feel the shape of the liner at all.
Is it equipped with a zipper? The beauty of our sleeping bag liners is their minimal weight and packed size, and a zipper would significantly increase both.
