Description

The THERMOLITE® Reactor Extreme liner is Sea to Summit’s warmest knitted sleeping bag liner. If your adventures take you to colder climates, the Reactor Extreme will add plenty of warmth to a sleeping bag. Plus in warmer weather, it can be used as a ‘stand alone’ sleeping bag. The hollow core fibres of the THERMOLITE® fabric work like a polar bear's fur and, along with the knitted structure, trap plenty of insulating air. Super soft and amazingly stretchy, the Reactor Extreme uses a heavier version of THERMOLITE® to provide extra warmth for an incredibly comfortable night’s sleep. Use one to build your cooler-weather sleep system and to help keep your sleeping bag clean too.

Frequently Asked questions

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.
