About The Product

Add warmth to your sleep system in cool or cold conditions: with our Reactor Liner. Using Thermolite® Pro fabric with infra red-absorbing ceramic pigments and Thermolite® EcoMade fibres , the new Reactor takes thermal performance to the next level. The stretch-knit fabric provides optimal comfort, and ensures the Reactor fits any sleeping bag. Choose between the classic Mummy and the Mummy with Drawcord - the footbox opening offers plenty of ventilation and the versatility of walking around camp while still wearing your liner if needed.

Technical Features

HEIQ Fresh

Sea to Summit Liners are treated with HeiQ Fresh FFL, a biocide-free, highly effective odor control technology that uses a bio-based Amino Sugar Polymer to neutralize body odor.

Thermolite Pro

Thermolite Pro has engineered hollow fibers like standard Thermolite but with the addition of permanent ceramic pigments that absorb the body's infrared rays and reflect them back to the wearer.

Thermolite Eco Made

The recycled Thermolite EcoMade fibers are made from 100% textile waste, are GRS-certified, and offer the same quality and durable lightweight warmth as their polymer virgin counterparts but with a lower carbon footprint.

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 performance. 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 pad 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 pad.
