We've only been using this product for a few nights, but I've already noticed a significant improvement. My husband and I are both hot sleepers, so this is ideal because it is lightweight while still providing a sense of security while sleeping. Because we all get a little chilly at night, we now need to use our comforter to go over it. When we just used our comforter instead of this lightweight blanket, that was never the case. I would recommend this product to anyone who sleeps hot.
