This is a pack of 2 fitted crib sheets. These crib sheets fit perfectly on my little ones mattress. Each corner has a 9" pocket making sure that it fits securely around the mattress. They are made of 100% jersey cotton and they are so soft. This fabric is great for Florida weather since it is thin, cool and breathable. These are gender neutral making them great for both baby boys and baby girls. One is grey and white chevron while the other is grey polka dots. These would make a wonderful baby shower gift! I am in love with Ziggybaby products.
