A sleek and stylish bag, the expandable zipper offers flexibility to pack light, or expand as needed. Comes with a removable, hanging closet to keep a week’s worth of clothes organized and easily accessible, while also providing compression. Features: + 27 Liters compact, 35 liters expanded + Removable hanging closet + Sunglasses pocket + Suitcase seatbelt + 4 secret pockets - passports and credit cards + Plush shoulder straps w back support and sternum strap + Water-resistant bottom + Deluxe drop-proof laptop storage (16" laptop) + Wrinkle free paper storage + Protected Glasses Pocket + Cable organization In my experience this bag works great either as a fully-stuffed carry-on in the overhead compartments, but will comfortably fit under the seats on airlines like Delta, Alaska Air, Air New Zealand, Air Canada, Iberia, and United if you like to pack minimalist. The tech pocket works great for my 16 Macbook Pro for work trips, and the closet is very helpful for keeping things organized in hotels. Excellent all-around bag and looks super sleek with the heather charcoal exterior! Bag has no defects and has been cared for extremely well.
