Sea To Summit Reactor Midweight Regular Sleeping Bag Liner - Beluga

Hygienic and comfortable sleeping bag liner in Beluga color, featuring a durable and pleasant-to-touch material. It can serve as additional insulation for a basic sleeping bag or as a lightweight summer sleeping bag.

Thermolite fibers, HeiQ Fresh FFL technology

Made from Thermolite Pro fibers, using infrared technology, allowing the material to absorb NIR radiation, which increases the temperature. The material dries quickly and effectively retains heat. The lining is coated with the HeiQ Fresh FFL odor control technology.

Integrated hood, arm openings

Using the liner increases the thermal retention of the primary sleeping bag by 6 deg. C. The product is equipped with an integrated hood with a drawstring for additional thermal comfort. The model also features snap-fastened arm openings, which do not restrict movement during sleep.
