Looking for a high-end wallet for men... any suggestions?

Goyard is also very popular for canvas, but you need to live near a boutique and they are quite pricey (double LV prices for canvas).

I come to find Louis Vuitton being best balance of functionality, quality and price. You can do either canvas or leather, depending on budget and preference
 
+1 on LV. They have quite a big variety in the mens section.
I might be bias since I just love LV, but I don't think anything beats SLG's from LV. Their canvas pieces are really durable. I have used my LV key pouch every day the past 5 years and it still looks brand new.
