I bought these sheets based on reviews and price. Very pleased with quality. Definitely cooling and comfortable to lay on. Very smooth, almost satiny, to touch. Got in dark gray, color very pretty. Great quality for the price.

The softest sheets ever! 💙
Color: 05 - Dusty Blue, Size: Queen, Color: 05 - Dusty Blue, Size: Queen
This sheets quality feels great! It feels a little heavy but comfortable. I love the way it just drops. It feels cool to the touch, and so so gently on my skin! I previous had gotten a 100% cotton sheets from this same brand and it feels soooo rough on my skin, but this one is great! Best money spent! Bamboo material! I'm never going back! I got the dusty blue, in the photo is looks gray because of light but I love the blue color, it looks great!

Comfy, cool
Color: 01 - Dark Grey, Size: Queen
This is my first time buying rayon/ bamboo sheets, and now I finally see what I've been missing. Very comfortable, soft, and feel really nice against the skin. Nice for this price point too. I took off one star because they do tend to wrinkle quickly, so I have to readjust them every night before going to bed. Also be aware that oil from your skin and hair products tend to stain them very quickly, and the stains are not easy to get out. But I'm ok with that as a trade-off for the comfort!

Look no further than! Buy these 💯
Color: 01 - Dark Grey, Size: Queen
Queen. Grey.
Beautiful. Nice snug fit. Feels like silk. Super comfortable, soft, almost buttery. And truly cooling fabric. The price point is a steal. I will be ordering these sheets in all the colors.
P.S. these sheets also laundered beautifully.
I’m very very pleased with this purchase.

Sheets
Color: 05 - Dusty Blue, Size: Full
Have been the best sheets I've bought, would totally spend the money again. They feel soft against your skin yet keep you cool and comfortable. Easily fits my extra thick mattress, only a little wrinkles during use. They offer some wonderful colors, went with a dusty blue and am completely satisfied with richness of color.
