Sea to Summit Reactor Plus Thermolite Liner - Compact - Black/Orange

Write a Review

The Sea to Summit Reactor Plus uses dual-weight Thermolite® fabric to increase warmth without weight penalty. The Reactor plus adds panels of 110 g/m² Thermolite® to the core body and foot areas to provide more warmth. While the Reactor Plus isn't marketed as a women’s specific liner, it’s compact length and additional warmth make particularly popular with women who seek some additional warmth to their bag.

  • Far warmer than Sea to Summit Reactor liner thanks to 110 g/m² Thermolite® panels without adding much weight
  • Sea to Summit quotes this liner as adding up to 20° F (11° C) of warmth, we agree it’s super warm, similar to wearing a down jacket to bed, although we have to add the caveat that lots of factors play into how warm it will feel to you!
