The Sea to Summit Reactor Extreme Mummy Liner is a sleeping bag liner that adds extra warmth and increases sleeping bag performance by up to 15°C.
With its super insulating 110g/m² Thermolite® fabric, the Sea to Summit Reactor Extreme Mummy Liner offers a spacious design that is slightly tapered from head to foot to reduce weight and increase thermal efficiency. The drawcord hood can be cinched down for extra warmth when required too. This knit fabric also has serious stretch to it, making the Reactor Extreme the ideal liner for the restless sleeper.
"I bought one of these years ago to add a few degrees to my cheap summer sleeping bag, and I still use it now. It's great, it adds so much more comfort than just using your sleeping bag (plus you just wash the liner rather then letting your sleeping bag get smelly). I can even get away with just using the liner on warm nights camping or bivvying." - James.
