Sea to Summit Reactor Extreme Liner w Drawcord
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.
