Very nice adidas jogging pants for boys. They are made from 100% polyester. The big ones fit as expected, they saw L (14/16)+ on the tag. My son is 13 years old, 125 lbs, 5ft 1in. and usually wears boys L(14/16)/XL(18/20) and can also wear men's small. I know that ordering clothes online can be frustrating because everyone's sizes are different. These Adidas pants fit just like the others and I would say they are true to size.
