Sea to Summit Reactor Extreme Liner
Description
The THERMOLITE® Reactor™ Extreme liner is Sea to Summit’s warmest knitted sleeping bag liner, capable of adding up to 25°F to your sleeping bag. 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 fibers 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.
THE REACTOR EXTREME IS PERFECT FOR…
- Backpackers whose sleep system will be used in colder climates
- Campers whose sleeping bags don't keep them warm as the advertised temperature
- Very warm-weather campers who don't need a full sleeping bag
- Campers or backpackers looking to extend the performance of a (perhaps older) sleeping bag into shoulder seasons
