Sea to Summit Reactor Extreme Liner

Sea To Summit's Reactor Extreme Liner +Drawcord is a sack sheet that increases comfort and thermal performance. The manufacturer claims an increase in insulation of around 15% in summer and 7% in spring/autumn. In our experience, this meat bag provides around 7/8°C of warmth. It can be used in a sleeping bag in winter, on its own on hot summer nights, or in a refuge.

For added versatility and comfort, this Reactor Extreme Liner features a drawcord at the feet and a slit to extend the arms.

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.
