Setting off
The laptop slides into its dedicated pocket, the water bottle into a side pocket. The rest of the volume absorbs a full outfit and enough to last until evening. Thirty liters is the capacity stated by the manufacturer: enough to head out loaded without going back home between appointments.
During the day
The side pockets for water bottles save you from opening the main compartment at every break. You grab the bottle in one motion, put it back, and carry on. The main material is polyamide, the lining polyester: two textiles that need nothing more than a damp cloth.
In the evening
Care comes down to one line: clean with a damp cloth, no washing or tumble drying. The bag is emptied, set down by the door, ready for the next day. One size only, so there is nothing to choose on that front — volume and pocket access will be what decide it.
