The THERMOLITEĀ® Reactorā¢ Extreme liner is Sea to Summitās 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. In warmer weather, it can be used a āstand aloneā sleeping bag. The hollow core fibers of the THERMOLITEĀ® fabric work like hollow polar bear or caribou fur ā along with the knitted structure, this traps plenty of insulating air. Super soft and amazingly stretchy, the Reactor Extreme uses a heavier version of THERMOLITEĀ® Ā to provide extra warmth for an incredibly comfortable nightās sleep. Use one to build your cooler-weather sleep system and to help to keep your sleeping bag clean, too.

DOES THE REACTOR EXTREME LINER...?
- Add 25Ā°F / 15Ā°C to any sleeping bag?Ā Not necessarily. There are a lot of factors involved in the thermal performance of a sleep system, starting with the insulation value of your sleeping pad. Read moreĀ HERE.
- Work for backpacking?Ā For most backpackers. The Reactor Extreme weighs 13.9 ozs ā a reasonable trade off in weight/thermal performance for occasional cold-weather backpackers. Weight-conscious performance users may opt for a Spark Sp 0 / Flame Fm 0.
- Need special care when being washed?Ā No! The Reactor Extreme can be washed in a washing machine with normal supermarket laundry āsoapā; just avoid fabric softeners as they will reduce the wicking performance of the fabric. You can dry it in a dryer, use cool or low heat.
