You have to wonder what it is that makes the difference between man-purse and man-bag? Man-bags can be anything like a backpack, big messenger bag, duffel bag, or an Alice pack. But sometimes you have to say, "Is this too gay for even me?"
I think your bag meets man-bag qualifications, Cormac. It meets the criteria of being larger than a normal women's purse, it has a rugged look, and it has the word "Hunting" on it.
