Thick denim, excellent quality, will buy again.Exactly what I was looking for.I usually like a carpenter fit on my son sense he is a tall ten year old boy but this cut was horribly wide all the way to ankle. Don't purchase if you are looking for a long length JeanNice jeans but did tear at the knee very early on.Large. Kept to be worn next school year. Legs are very wide.They where to large for my liking, and to big for my leg size, it needs adjustable waist bandTerrible sizing!! Not a recommended buy! Odd fit and WAY too small for the sizes i triedMy son enjoy the pants for school time .
