UltraCool 涼感被

The lightweight version actually keeps me comfortable without that clammy feeling, even when the AC is off. It's noticeably cooler to the touch than my old down comforter, and the nylon/spandex shell doesn't bunch up overnight.

I sleep hot year-round, so I grabbed the lightweight version for summer. The NASA-engineered fiberfill keeps me comfortable without that sweaty, trapped feeling, and the nylon/spandex shell is noticeably cooler to the touch than any cotton duvet I've tried.

The cooling nylon/spandex top actually stays chilly to the touch all night, which I didn't expect from a comforter. I've been sleeping through without flipping the covers for the first time in months.
