I sleep with my window open and fans blowing on me through winter, fall and spring. I hate having my room air too war, but there are lots of times I want my bed warm. This blanked is perfect because it warms up quickly and even at a setting of 3 (goes 1-10) it provides enough heat that my feet do not get cold and my husband has stopped using the extra blanket at his feet. Even if you do not put the heat on it provides nice insulation from the wind.
