The Studio 2 Large in black and gold is the best bag I have ever used to travel. It is sturdy and comfortable. The side pockets are perfect for stowing my wallet, phone, boarding pass, and passport for quick secure placement when juggling these items through the airport and customs. The front zip section is the best for my toiletries. As a woman, I pack a lot of hair, skin, and bathing products. The front compartment has many pockets to hold everything. It also has enough room to stow baggies of liquids. The internal bag holds shoes, books, etc. It contains two net bags for a water bottle and umbrella. When I travel, I use these to hold a pair of sandals and my important at-the-ready items - contacts, solution, meds, glasses, etc. The twisted knob closure provides added security and looks great, too. This bag fits easily under the seat in front of you when flying. I enjoy this bag so much more than my LV tote and duffle because I can put it on my back. I am hands free without bulk. If you are flying, you want this bag.
