Reactor Sleeping Bag Liner with Thermolite Pro Fabric

Cool nights get easier with the Reactor Liner in your bag. Thermolite® Pro fabric uses knitted hollow-core fibers plus infra red-absorbing ceramic pigments, and Thermolite® EcoMade fibers round out the build — together they push thermal performance further than the previous version.

Stretch-knit fabric is the reason it fits any sleeping bag you own. Pick the classic Mummy, or the Mummy with Drawcord: the footbox opening ventilates well and lets you pull the liner up and walk to the bathroom without stepping out of it.
