Frequently Asked questions

Does the Reactor liner have a zipper?

No - to keep weight and packed volume down, we did not include a side zipper. Snaps at the shoulders mean a wider opening than some liners for entry and exit (and the drawcord footbox allows you to vent your feet or hitch up the liner and walk around camp

Can the Reactor liner be machine washed?

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

How much warmth does a Reactor 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 mat insulates (not the same as its R-Value) and a lot of other factors. You should see a boost of several degrees Celsius / Fahrenheit if the liner is used with an appropriate sleeping bag and mat
