видавший виды – worn, seasoned, world-wise

No etymology, really, since it’s a stock phrase rather than a word. But when I ran across it, referring to a coat worn by one of the characters in Jana Wagner’s post-apocalyptic debut novel, I immediately liked it. As if the coat were saying, “Hey bub, I’ve seen things.”
