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.

This thing is awesome, I can wrap my whole body up and still have plenty of comforter left. Keeps me nice and cool no more night sweats. Perfect thickness and you cant beat the price. Absolutely love the color fit perfectly with my room and colors already.

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.
