Sea to Summit Reactor Fleeceweight Sleeping Bag Liner

Boost the warmth and performance of your sleep system with the Reactor Fleeceweight sleeping bag liner. Built with Thermolite® hollow-core fibres and grid fleece, it traps and reflects body heat to add up to 8°C / 14°F of extra warmth with minimal weight or bulk.

The stretch fleece construction and integrated arm openings provide freedom of movement, while snap attachments pair seamlessly with Sea to Summit sleeping bags for easy entry and exit. Quick-drying, easy to clean and treated with HeiQ Fresh odour control, it stays fresher for longer on extended trips.
