Women have the Birkin, what do men have?

Sorry I don't think I asked correctly. It seems like the guy bags aren't as trendy/classic as the trendy Birken. Seems like the Birken, Kelly, Constance are the only real classics.
The Hermes HAC is very popular with men, especially in the larger sizes. It is often sold in the men's section if it is even displayed in the boutique. If I'm not mistaken, the HAC is the traditional steamer luggage that inspired the Birkin bag.
