I have these in Joey Big T and LOVE them, so soft! I normally wear 28's in Joey and Bobby Rigid. These run a little small, but not a whole size. When I tried them on they were a little snug...more so than any of my other Joey's...but not enough to justify moving up a size. But then I went and washed them and very stupidly put them in the dryer for a whole cycle on HIGH...I don't know what the hell I was thinking...and it took a bit of manuevering to get those suckers buttoned!
) But, I know they're going to stretch out, so I'm thinking they'll fit like my Bobby's do...slightly more snug than Joey's.
Can't speak for stretch...I don't own any.
