I found this 65L Duffel Backpack is a perfect size to work as a travel bag loaded with 2 medium packing cubes, 2 small packing cubes, wash pouch, Shoe pouch, tech pouch. Also, I can add a 5L Camera Sling bag. I like the size because the duffel bag does not bulky and the designer makes many handles and carry belts in all direction. The benefits make me feel well-organized not only for travelling but carry 3 sets of 10L Camera Sling Bag or 4 sets of 5L Camera Sling Bag carrying wireless transmitter & receiver in addition to one 5" field monitor. Therefore, It is a good organizer. Finally, I must say that the quality of material used make me have a very good impression. Also, the design is the most important factor that I have purchased 2 Black and 1 Sage of this 65L Duffel Bag.
