Nizar-I personally use a North Face Base Camp Duffel. We have a few sizes of these, but usually for 2-3 day trips I'll grab the Small one.
Not what I'd call "professional" looking luggage, but practical and bulletproof.
I'm Holding out for a sale on Rodd & Gunn luggage. Would love one of their Large Weekenders!
