Supposedly mandalorian armor, though I don't think we ever see it.

You see it plenty in the online games, like Star Wars: The Old Republic.  I bet we see some on the bridge of Vader's flagship in ESB when he's talking to a bunch of bounty hunters.  But of course we aren't told what it is, nor is any of it subjected to blaster fire.

Stormtroopers have pretty crap armor as far as blasters are concerned.  There also aren't a lot of conventional munitions or explosions in this universe, to justify the wearing of such armor for other reasons.  I'm pretty sure that having anyone wear good armor, would have gotten in the way of the pew pew pew storyline.  People would have been like "Huuuh, why does he have good armor?"

Fortunately for Star Wars at the time it was made, modern infantry battlefield armor wasn't really a thing yet.  Even police armor was probably in its infancy.  Some of us however knew a little bit about medieval armor, thanks to AD&D.  I'm not sure at what age I began wondering about things like, "can crossbow bolts go through armor?"  (Yes!)  Followed by, "can musket balls go through armor?"  That question is basically where AD&D ends and some other kind of game would begin.  A sort of cross-genre RPG question.

I don't remember noticing or caring about the "arms vs. armor" issue as a kid, but sometime as I grew up, it began to be on my mind.  Of course eventually they just ruined the whole franchise with the prequels anyways, so....

Yes, Boba Fett has Mandalorian armor, but we never see it stop a blaster.
