Sea To Summit Reactor Sleeping Bag Liner Standard Mummy

Brand:Sea To Summit

Code:A3202-Yellow

Add warmth to your sleep system in cool or cold conditions: with the Reactor Liner.

Using Thermolite® Pro fabric with infrared-absorbing ceramic pigments and Thermolite® EcoMade fibres, the new Reactor takes thermal performance to the next next level. The stretch-knit fabric provides optimal comfort and ensures the Reactor fits any sleeping bag. Choose between the classic Mummy and the Mummy with Drawcord; the footbox opening offers plenty of ventilation and the versatility of walking around camp while still wearing your liner if needed.

Features:

  • Thermal boost to retain heat and warmth, extending the performance of your sleeping bag in colder conditions.
  • Thermolite® Pro technology uses knitted, hollow-core fibres and infrared-absorbing ceramic pigments to reflect your body's heat back for enhanced warmth and comfort.
  • The classic Mummy version has practical openings in the shoulders to allow the user to stretch his or her arms out.
  • Snaps at shoulders to secure and stay in place.
  • Packs small, making it the perfect backpacking companion.
