Cheap junk I think the material but it was cheap so seems like it's expected don't worry. After 2 weeks it started to fade noticeably and this photo was taken within a month of purchase in April, the summer sun hadn't even come up on it yet. Threw it away in June after telling the seller it was rubbish. In addition to fading, it retains water, making it look like a sagging diaper unless emptied. I don't normally give bad reviews, but stay away from this product.
