The Sea to Summit Thermolite Reactor Fleece sleeping bag sheet is designed to double up as your sleeping bag for added warmth. All you have to do is insert it into your sleeping bag and slip into it. If you get a bit chilly at night, then this bag sheet is an economical alternative to gain warmth.
The manufacturer claims a temperature gain of 18°C. However, we recommend a maximum gain of 14°C. For the less chilly among you, the Reactor Fleece Liner can be used in place of a sleeping bag for warm-weather bivouacs in summer.

Left-side opening, when you're in the bag. Complementary to a 5°C to 0°C sleeping bag. The sensation of warmth is immediate. Must be removed from sleeping bag to roll it up. (Translated review)
