I've only used this about 3 or 4 times since it got cold. I'm selling it because my child has outgrown it. It's a men's size M, but it can also be worn by children around 160-165 cm tall. The collar lining and inner pocket are made of corduroy fabric, and the lining has a refreshing and stylish blue stripe design. Please check the images for the fabric and size.
