So far it has been great. Breaths good and regulates temperature. Since I’m a hot sleeper, it helps me stay asleep and that is difficult as well. I’m a veteran and a Fire fighter, so my sleeping habits are irregular. The best thing I’ve found to help me is bamboo sheets, a 3” cool foam topper, a/c at 67 deg and now this comforter. If your in the same boat, hope this helps you too!
