100% Polyester Water-repellent finish Length: approximately 82cm, Sleeve length: approximately 49cm The size is 140cm, but the length is long, and the width can be adjusted with snaps (allowing it to be worn while carrying a backpack), so my child was able to wear it until they were 160cm tall. It can be put on and taken off with a zipper, so it's easy to wear, and my child loved it. It folds up small and is lightweight and convenient, so it's reassuring to have it on hand for sudden rain. It was a favorite item, so there is some wear and tear, but it's a good product, so I'm putting it up for sale.
