Sea to Summit Reactor Liner

Sea To Summit's Reactor Liner sheet increases the temperature inside your sleeping bag. Sea To Summit claims an increase in insulation of around 12% in summer and 6% in spring/autumn. In our experience, this meat sack adds around 4/5°C of warmth, which is no mean feat in cold weather!

The Thermolite fabric used is as effective as fleece, but has the advantage of being lighter and more compact. This bag replaces the traditional meat bag made of fleece, cotton or silk. For use when hiking, camping... HeiQ Fresh technology provides long-lasting odor control.
