Looser fitting rashguards

[Foppa21]

Hi all,

I see that rashguards seem to be a bit looser around the middle. I know that Tatami has a "dad bod" cut. Anyone know of other brands or cuts that are like this? I'm looking at the stuff that some of the guys in b Team wear where they look looser around the middle. Is there a specific cut or are they just getting something a size or 2 bigger?

Thanks
