"Big boned", from guys? Come on guys, really? Big boned? Just come right out and say it, we are guys....
I have a BIG *** Belly! Yeah, you can see the ripple of muscle still in my calves and I guess they would be quads as well. Everything below the waist I look like I'm still 20. Above the waist is a different matter. Oh, yeah, and grizzly bear is exactly how my wife and girls describe me too, though I've seen worse, much worse.
I've looked up some of these shirts folks are mentioning here. Tight can be described differently depending on the person. I like my t-shirts big, really big. I'm 5'10" and 230 lb, most in the belly. It's not that t-shirts don't fit. I just like how loose and maneuverable a 3X t-shirt is. These shirts in this thread that I've looked up don't look tight, just form fitting. No one wants to see that form when I'm walking towards the pool, hehehe. Form fitting to someone else may not be tight. Form fitting to me is tight, really tight. I'm not too sure about these shirts that I'm seeing mentioned in this thread.
Though, if I'm going in the pool, I'm going in the pool. I'll be up to my neck in water, so I'm not too sure if I would worry about wearing a shirt. I wear a shirt when I take the girls to the lake, but that is just basically wading around in the water near shore, not doing any actual swimming in the water.
I haven't been to a public pool since the old belly matched those legs of steel I still have, LOL.
