I think this is more for "sporty" and "regular" packed guys, not if you are "very" gifted.
Triangle part for your pack is limited in size, because the rubber belt is very low rise, so not much space upwards... (all of seobean underwear are low rise, but this is more!)
Comfortable though, I'm "regular" sized, but I think if you are only 'sporty" gifted, it is the equivalent of push-up bras for women ;) go for it!
Don't buy these, if you have bit bigger belly, it will look funny on you!

Oh, I'm european, size L and seobean L is right for me.
