The DOWNCOOL Cooling Comforter Set (Queen Size 90”×90”) is a fantastic choice if you tend to sleep hot. The comforter uses advanced cooling fabric technology that absorbs body heat and helps reduce skin temperature by a few degrees, making it ideal for summer or warm climates. The material feels cool to the touch, lightweight, and breathable, so you stay comfortable without feeling heavy or sweaty. It also features moisture-wicking and quick-dry properties, which help keep the bed fresh throughout the night. The set includes 3 pieces (comforter + 2 cooling envelope pillowcases), and the pillowcases add an extra cooling effect around your head and neck. The fabric is soft and skin-friendly (often OEKO-TEX certified), making it safe for everyday use. It’s also machine washable and durable, maintaining its cooling performance even after multiple washes, which makes it practical for long-term use.

Cool and comfy

Team Name: Cooling Comforter, Size: King(104"x90"), Color: 01grey

So comfy, lightweight, soft and yes, cool to the touch. Doesn’t stay cool though for long exposure but great for sleeping with animals or others.

Wonderful

Team Name: Cooling Comforter, Size: Full/Queen(90"x90"), Color: 01blue

Works wonders for cooling! Very breathable. It’s “slick” so slides off the bed overnight if you move a lot in your sleep.
