Reactor Midweight Sleeping Bag Liner with Thermolite Pro Fabric

Add real warmth to your sleep setup with the Reactor Midweight. Its Thermolite® Pro fabric uses infrared-absorbing ceramic pigments and hollow-core fibers to hold body heat, pushing up to 6°C|11°F of extra warmth into your system without much bulk. Stretch-knit fabric and arm openings give you room to roll over, so the liner suits sleeping bags of any shape. Drying time is short, cleaning is easy, and HeiQ Fresh odor control keeps it usable between washes, which means fewer trips to the machine for your bag itself.
