Frequently Asked questions

Can the Reactor Fleece liner be machine washed?

Yes. It can be washed in a machine with normal supermarket detergent - but avoid fabric softeners which reduce wicking performance. Machine dry on a cool/low setting (no dryer sheets) or air dry

How much warmth does a Reactor Fleece add to a sleeping bag?

This depends on how well your sleeping bag retains warmth (not the same as its temperature rating), how well your pad insulates (not the same as its R-Value) and a lot of other factors. You should see a significant boost if the liner is used with an appropriate sleeping bag and pad.

How does the HEIQ-Fresh work?

The liner is impregnated with bio-based amino sugar polymers that absorb and neutralize odors. When the liner is washed, the compounds that cause odor are released, and the polymer is ready for the next use
