These XL twin sheets do NOT fit my xl twin mattresses. They are too long length wise and too short width wise. I have tried to use them several times and each time they do NOT stay on the mattress for even one day. I am very unhappy with the sizing and if I could return them I would. Was just a waste of good money in my opinion

Not Happy - Faded

Size: Twin XL, Color: 08 - Dark Blue, Size: Twin XL, Color: 08 - Dark Blue

I really wanted to love this but ended up super disappointed in this cover sheet. It was a generous size & nice fabric BUT it faded in the center of the sheet where my child slept on it. Here are pictures to show the side of the sheet against the faded area. I would not recommend it although I like that it's organic.

Wonderful knit sheet

Size: Queen, Color: 01 - White

I ordered the white queen size fitted sheet. I've washed and dried this sheet (on low) and it is wearing well. Actually not wearing at all---it's as good as when it was brand new. The packaging is nicely done, the elastic holds, the material is smooth and comfortable, it's just plain a good thing. Our queen mattress isn't super high, maybe 12" and it fits fine with a little tucking at the bottom. For sure this sheet would fit a much higher mattress. The fact that I had to cinch the bottom a little bit does not take away from how lovely this sheet is. I would definitely buy again.
