I am 6' 180lbs or so..I vary from like 175-185 or so. I wear a 34x34 jean and XL T Shirt/Large regular shirt. In Volcom I wear Large pants and a Large jacket. The XL jackets are to big for me usually. Medium to small, Large just about right! Volcom has a few different "fits" for there clothing, make sure you get the right one for what you want!
