I said same fit as PI stuff so if you wear an L in PI or similar you would likely wear an L in Ibex. In other words, I gave you a standard to compare to based on how you like your fit. My size won't tell you much but fwiw I'm 6'3" and 200lbs. I wear large in PI and Ibex but one of their reps said he was 6'2" and 200lbs and wears XL. Perhaps he has massive pecs or something. If I listened to him I would be making an exchange.
