The elastic is not rough but it feels durable and not overly to tight or something that would irritate his skin. The waistband actually does stretch but is more comfortable than regular boys briefs. These are super soft and comfy.

Quality is decent but they run small. I love all the colors and patterns; they are just too cute; super soft.

Size 6-7 (small) are a little snug on my just turned 6 year old son. I'm used to the boys small, medium, large sizes mainly judging by fruit of the loom. These have large, extra large and extra extra large which sounds like it would fit a jumbo jet.

These are too small in the rear end for my son. They come up about an inch above his rear. About 4 pairs shrunk slightly and will work, while the other 6 shrunk at least 2-3 sizes.

The waist isn't elastic, my son wears 3t in everything, and he is tall and slender. The pattern is cute and my boys liked them but then they both starting getting a rash on their butts. They have no elasticity.
