Yea, I'm not a huge fan of them stating "synthetic leather", but there are varying materials which will all fall under that broad category. So long as it's more of a suede-ed type of synthetic and not a plastic-y, shiny, painted type of faux-leather then it can last a while. The painted on stuff (think Sideshow Batman blue comic PF trunks from 2015/16-ish, Batman 1989 PF cape) all deteriorates quickly in a warm climate.
I suppose we can always replace it with a new material in time, but I'd rather not have to do that.
I still have to figure out how to replace the trunks on Batman...
