So soft and amazing quality
Color: 12 - Light Beige, Size: Twin
I can't tell you if they're cooling or not yet. The weather took a turn for the cold so I haven't put them on the bed yet. But the quality..omg it's exceptional! These are insanely soft! Not slippery like satin but not scratchy like percale. They're like the best of both worlds..light as satin but nicely weighty like percale. I don't know what kind of sorcery this is but these are literally better than those 6-zillion count Egyptian cotton sheets that cost more than the GDP of a small nation. These are exceptional!! Soft as butter but still feel like they'll last a while and not let you fall out of bed like silk lol.
When you fold them, they snap nicely.
They seem to have a lived in look..like they'll never be utterly wrinkle-free but who cares..they're smooth, soft and supposed to be cooling.
I never thought I'd find anything more comfortable than cotton sheets but these are even better.
The colors are ok. Pretty basic but they are true to life..some others look different online than when you get them..not these colors online are accurate.
This was a great deal and I'd recommend a thousand times over!

Cool and Comfy
Color: 01 - Dark Grey, Size: Queen
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!
