One space for the things you'd rather not carry loose.
The Mono is a single pocket: one open compartment that takes whatever the day or the trip needs. Toiletries and an electric toothbrush for a few nights away, a tangle of chargers, or just the loose things that otherwise end up at the bottom of your bag. Two zippered pockets along the inner panels hold the small items you want to find first.
Half-zip opening, so it lays open when you need it and closes flat when you don't.
Dimensions: 20 × 10 × 5 cm Internal: single compartment, two zippered inner pockets
