# Ortlieb Urban Daypack 15L — The Minimal Business Backpack

*Waterproof, compact, and just big enough for a laptop, tablet, and nothing more.*

> Willem fits his entire business in this 15-litre backpack: laptop, tablet, cables, notebook. Waterproof for Amsterdam cycling, minimal enough to force discipline about what you carry.

The Ortlieb Urban Daypack 15L is a roll-top waterproof backpack. It's small — deliberately. At 15 litres, it forces you to carry only what you need: a laptop, a tablet, a small peripherals case, a notebook, and a phone. Nothing more.



The waterproofing is genuine Ortlieb quality — the same company that makes panniers for bicycle touring. In Amsterdam rain, everything inside stays completely dry. The roll-top closure means no zippers to fail.

The constraint of 15 litres is a feature, not a limitation. It prevents the backpack from becoming a portable storage unit. You audit what you carry. Everything earns its place.
