So far I've ordered many different brands of Asian trunks. they all have their ups and downs and I've noticed that SEOBEAN seems to be a pretty popular brand, so I decided to see for myself and order these. first off, as for the people giving these a bad review because of the sizing, it clearly tells you in the description that you must order one size up from what you'd normally wear in the USA or Europe. So in the USA I wear size SMALL so I bought a MEDIUM in these. even still, these are meant to be tight fitting, I am 6'3 and around 145 pounds, so I'm very thin, and the mediums barely fit me, so make sure you know what you want. I've noticed that most Asian underwear isn't made of cotton, which is good because they're usually tight, but since these are made of cotton, make sure you get your sizing correct, otherwise they won't fit. the waist stretches well, but the leg openings don't, so like I've said, get one size up from your normal size. they're also pretty low-rise and barely cover your pubic region and same for the back, so make sure you know what you're getting yourself into. to be honest, these aren't the best Asian underwear for the price, but theyre still really cool.
I am normally a size Medium/32 inch waist in American pants/jeans/underwear. I purchased the XL and found that even though the measurements were similar to other SEOBEAN trunks, they had a MUCH lower rise. Especially in the back--very tight and barely enough fabric to cover, so there was some "butt-crack" peeking out. it's possible that this pair was just a random mistake. Not sure, but here are the measurements I got for the XL: Waist=29 inches, and side height=5.8 inches when laid flat. These might fit someone who is normally a size Small.
Looks great if you are in shape.
