Sea to Summit Thermolite Reactor Extreme

The THERMOLITE® Reactor Extreme liner from Sea to Summit is their warmest knitted sleeping bag liner. By utilising hollow core fibres and a knitted structure that effectively traps insulating air, it can provide substantial additional warmth for colder climates. Additionally, it can double as a 'standalone' sleeping bag for use in milder weather. Constructed with a heavier version of THERMOLITE® fabric for superior comfort, the Reactor Extreme is both incredibly stretchy and soft to the touch. Use it to build your low-temperature sleep system and maintain the cleanliness of your sleeping bag.
