These are some good basic jeans

Quality Level: Comparable to the best jeans of Old Navy/a bit thinner than GAP's

Cotton: the cotton is hard when it first arrived, after a few wash, its softens up.

Fit: VERY SLIM (all the way to the end) If you son has 'very thick/fat' legs, they will look slightly like skinny jeans (the top part of the jeans will look just like the top part of skinny jeans). If your son has thin legs, they will look just fine. My cousin has rather very thick/fat legs, and he felt they were a bit "too slim"

These seem like good basic jeans, and for currently, a good price.
