I bought these for my so who is 12 years old and only a little fat and he says they are very tight. I think part of it has to do with style, and it's struggling a bit with the transition from boy's underwear to teenage/men's underwear. He doesn't wear them every day but he will wear them so I only rated them 'good'.
