How many degrees does this add to a sleep system?

Best Answer Responded on

The Sea To Summit Reactor (item# STS 0085) will add 15 degrees, and the Reactor Extreme adds 25 degrees. They make fantastic gear, and if that's what they claim, I have no reason to doubt that their liners perform to specs.

The reactors cost way too much and everyone says they are not that warm. You need to suggest something you've tried!

The reactor extreme is a good liner, I was hesitant at first but when paired with a sleeping bag it adds warmth for sure. By itself it hardly does anything so it would be decent for summer. Packs to about the size of an eno double nest
