It's winter, it's cold, and you want to be warm, but then TOO WARM. Hot flashes are the worst but thrilled to find this blanket, I keep it above the covers, above my head on another pillow, when I get one I just pull it down over me and its instant chill, it lasts for about 15 minutes then still stays cool but not as cool. Then I put it back aobve my pillow and let it "recharge" while I warm back up under the covers. Im looking forward to summer, will update my revoew then.See full review
