Tortuga backpacks combine the best features of backpacks and of suitcases into a line of carry-on-sized travel backpacks.
Suitcases are made for airports and offices, not urban exploration. Try dragging one over the cobblestone streets of Paris or up a flight of stairs to the apartment you rented.
Hiking backpacks don't work well either. Every "backpacker" carries one, but these bags are too big to qualify as carry on luggage and don't keep your stuff organized.
We couldn't find the perfect travel backpack. So we made it.
