Query: Tougher than our grandson

After watching our grandson blow the knees out of various school uniform brands, we have found Dickies to be great. They are durable and up to the challenge of a very active boy.This was our first year moving up to the "big boy" sizes. One word of caution: the size 8 Dickies no longer have the adjustable waist feature that the 2-7 sizes had. For our skinny grandson, this is essential. Other reviewers have mentioned that these pants run small - that "Slims" are too slim - but, though the slims were closer to a fit, he still needed the adjustable waist.We wound up returning what we bought and found some uniform pants with adjustable waists at a local store.
