I have the Sport D Duffel, but
your requirements maybe different.

No.... actually Ive thought abt a good bullet proof
duffle as well. As long as the duffel could also be
worn backpack style and had shoulder straps and a waist
belt.

Can your duffel be worn like a backpack....and does it
have shoulder straps AND a waist belt?

I actually wouldn't mind the one big open space of a
duffle..... but I definetly want to wear it backpack
style if needed...hence the question above.
