Sea to Summit Reactor Fleece Liner

Sea to Summit's Reactor Fleece Liner +Drawcord is the warmest bag in the Reactor range. It increases insulation by around 22% in summer and 10% in spring/autumn. In our experience, this meat bag adds around 10°C of warmth. It can be used as a sack sheet or as a sack alone for use in warm conditions:

• Winter use: provides extra warmth in addition to your synthetic or down sleeping bag.


• Summer use: you can use it on its own, as a lightweight sleeping bag.

It has a sarcophagus shape with a hood and two side zippers for easy access and temperature control. A drawcord at the feet for a better fit and more versatility.

The fabric used is a combination of Thermolite and checkered fleece, offering a smaller, warmer sheet than a traditional fleece bag. HeiQ Fresh technology provides long-lasting odor control.
