Where can I get a good leather belt?

I want to buy a nice leather belt. Not pleated or braided just normal leather in black and another in brown. Normally I'd go to walmart or some **** but I want something stronger like kangaroo leather or something. Have you ever seen the movies where the hero zip lines with his belt? It turns out that that breaks the belt... and your leg sometimes so i need something nice looking that wont break when I do that.
