Description
The Reactor Fleece Liner is constructed from Thermolite® Pro hollow-core fibers, arranged in a grid pattern, to provide our warmest sleeping bag liner and form the core of a high-quality cold-weather sleep system. You can regulate the temperature using zippers at the shoulders and a drawstring at the footbox, which are also fully compatible with Sea to Summit's Free-Flow Zip system for sleeping bags. The versatile Reactor Fleece Liner provides comfort across multiple seasons or can even be used as a standalone sleeping bag in warm weather. Additionally, the drawstring at the footbox offers both good ventilation and the option to move around camp while still wearing your liner, if needed.
