FAQ
Suitable for use with a rectangular / wide sleeping bag?
The knitted fabric of the Reactor is so stretchy that you won’t feel the shape of the liner at all.
Equipped with a zipper?
No - to keep this sleeping bag liners at a minimal weight and packed size we did not include a zipper.
Washed in a washing machine?
Yes - you can wash your liner in a washing machine with normal supermarket laundry ‘soap’ and dry it in a dryer, using cool or low heat. Fabric softeners will reduce wicking performance of the fabric.
