Ortlieb Commuter Urban 21L Daypack Ink, One Size

Strike a balance between casual, conventional packs and professional office bags with the Ortlieb Commuter Urban Daypack. This durable bag is a bit more tidy and sophisticated than standard daypacks, but is built just as tough (if not tougher), thanks to its waterproof Cordura exterior, and rubberized that holds up to wear and tear of daily commutes. It features padded, adjustable shoulder straps with a removable waist and chest strap to cinch things down when you're on your bike and weaving through traffic, along with TPU pads along the back panel to cushion your load. The outside stays minimal, with a single side pocket for your phone, and a couple of assorted loops that can secure your U-lock.
