Brain Sleep Comforter EX Perfect Cool

This proves not only how innovative the Brain Sleep Comforter EX Perfect Cool is but also how desperate the Japanese are for something that will give them some precious hours of cool sleep during the rainy season and the humid summer that follows it. And this deceptively plain light comforter delivers it big time!

Available in two colors (saxe blue and light gray) and in three sizes (for single, semi-double, and double beds – see the dimensions below), the Brain Sleep Comforter EX Perfect Cool comprises four distinct sheets of different materials (polyethylene, nylon, polyurethane, and polyester) arranged in a way that absorbing both your sweat and the environmental humidity to keep you cool.
