I think Ibex runs big, in general and their sleeves are always quite long (which I know is a godsend for many!).
Trisk - I don't know what size my Pez vest is (I'm at work, it's at home!), but I can check for you tonight. I do know that my vest fits looser than my Shak's, so if they are the same size, then it could be that the Pez runs larger. That's my guess, but I can't say for sure without checking (plus, vest sizing could be different than sweater sizing, of course)... I'm not much help, am I?
