im an inch shorter than you and about 20 pounds heavier and a have the xl and love it. i wear size 32 pants and i have no problem keeping the saga up. the xl should sit about an inch above your knee caps assuming you're the same proportions as me. the large would definitely be big enough but you shouldn't have any problem with the xl either.
Dude, you can see my pics, I'm 5'11 and my Scuba Too's are larges, and the Ecto's are xl.
If you're going to get Saga, don't fake the funk and just go as big as possible! Just use shoelaces as suspenders! haha.
Dude, we gotta get some new Jiberish so we can be thug and look like we're related to Eazy E when we're on the hill!"
"Yeah broski, after I stop this pretzel 4 I'll go on NS on my phone and buy some from BigSpence, I heard he has more in stock than AbstractMall!"
