could anybody explain me what is the tuff bag? Does it mean that you can carry heavy things in it or is it of a special material? thanks, Marketa
Both, probably. It's a brand name for a travel bag that resists tearing. One word: Tuffbag.
It's also possible that the original inventor of Tuffbags wasn't quick enough with the trademark office. I see "tuff bags" advertised elsewhere as well. Anyway, same thing: it is a very strong material for carrying heavy items as luggage.
