Crafted with a double-sided design. One side made from a polyamide performance blend that’s instantly cool to the touch, and the other from luxurious TENCEL™ Lyocell for breathable, silky comfort. The perfect balance of instant cooling and all-night softness.

Where most cooling comforters stop, we’re just getting started. Designed with a 30% PCM (phase change material) fill, ThermaCool gel melts at certain temperatures, rapidly absorbing heat as the temperature increases under the sheets. The result is hours of cooling power.

We think our comforter looks great, but we wanted to make sure you could style your bedroom exactly how you want it. You don’t need a duvet cover for the ThermaCool comforter, but if you want to use one, we went ahead and included eight loops around the borders.

Filled with ultra-high-quality TENCEL fibers, ThermaCool absorbs 68% more moisture than polyester, wicking it off your skin all night long. When tested in extreme humidity conditions, TENCEL outperformed polyester, cotton, and wool fills, creating the dryest sleeping surface of any other material tested.

Dosaze ThermaCool Comforter uses adaptive Phase Change Materials (PCM) to regulate temperature—absorbing excess heat when you’re warm and releasing it as you cool. Unlike most cooling blankets that rely on surface fabrics alone, ThermaCool is designed for consistent, all-season comfort.

We're so confident in our Cooling Comforter we offer a 60-night guarantee. If the ThermaCool Cooling Comforter isn't what we claim it is, you can feel confident with our hassle-free returns and shipping program. No hidden return fees or costs.
