Habing read alot of posts here about sporrans I think the Buss Kidder and Freelander sporrans probably have the best capacity. I have one commercially made sporran that I rarely wear because the stiffness of the front and back make it uncomfortable to wear. My everyday sporran and dress sporran I made myself. The everyday sporran is soft jacket grade leather and closed it measures 6 inches wide by 8 inches high when flat and has a 3 inch gusset. It holds quite a bit.
