Yeesss...
Such a lovely soft lavender! Cooling and soft and wonderful. I sleep hot and have night sweats (post menopause is a witch!), but this little comforter kept me cool and dry. I did notice that it wasn't effective with a top sheet underneath it. You really need it to be directly on the skin for the cooling effect. Besides this (and the price) I have no regrets. Will definitely buy again, if it goes on sale.

Very thin
Color: White, Size: King (104''x90'')
This is really cute but just beware it’s super super thin. The fabric is soft and it feel breathable but it’s very light and thin
