The Fitted Sheet White is not made of our signature crisp cotton, but of high quality 200 TC organic percale cotton. Percale sheets are cotton sheets known for their signature tight weave. The word “percale” refers to the specific type of weave used to produce the sheet and not the material it's made from. Sheets woven in this manner are luxurious and smooth. Tonal Embroidery of our logo in right corner. 100% Organic Percal Cotton, 200 TC. Made in Portugal.
