  • 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. In warmer weather, it can be used a ‘stand alone’ sleeping bag. The hollow core fibers of the THERMOLITE® fabric work like hollow polar bear or caribou fur – along with the knitted structure, this traps 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 to keep your sleeping bag clean, too.

    Features:

    • Stretchy, Thermolite® fabric is incredibly comfortable.
    • 110g/m² fabric is warmer than the 80g/m² Thermolite® used in the standard Reactor.
    • Works like your favorite cold-weather base layer to trap insulating air and increase warmth.
    • Easy care – no special soap is needed.
    • Significantly improves the thermal performance of your sleeping bag.
    • Comfortable stretchy fabric.
    • Keeps sleeping bag clean.
    • Machine wash and air dry - Avoid fabric softeners & dryer sheets to maintain wicking performance.
    • Packs into its own Ultra-Sil™stuff sack.
    • Easy to wash and helps to keep your sleeping bag cleaner for longer.
    • Perfect for:
      • Backpackers whose sleep system will be used in colder climates.
      • Campers whose sleeping bags don't keep them warm a 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 order) sleeping bag into shoulder seasons.
