Layer up for the chilly seasons

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.

  • Add 25°F / 15°C to any sleeping bag? 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 more HERE.
  • Work for backpacking? For most backpackers. The Reactor Extreme weighs 13.9 ozs – 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? No! The Reactor Extreme can be washed in a washing machine with normal supermarket laundry ‘soap’; 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.
  • 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
  • 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
  • Dimensions: 82 inches (208 cm)
  • Stuffed sack size: 6.5 x 4.5 inches (17 x 11.5 cm)
  • Weight: 14 ounces (399 g)
  • Imported
