What is bagjack?

bagjack is a German bag and accessories brand founded in Berlin in 1997 by Peter Brunsberg. It began with messenger bags made in a loft in Berlin Kreuzberg and has grown into a label known for highly technical, functional designs.

History

A defining moment came in 1999, when Brunsberg met the founders of ACRONYM at the ISPO trade fair in Munich. The meeting led to a long running partnership; a belt system developed in house by bagjack was used in ACRONYM's Kit 001.

Products and positioning

bagjack is known for utilitarian detailing and modular construction:

  • Messenger bags, backpacks and slings
  • In house strap and belt systems
  • Hardware such as AustriAlpin buckles
  • Modular designs that users can configure

All products are designed and manufactured in the brand's own factory in Berlin, giving it close control over materials and construction.

Distribution

Japan has become a major market for bagjack, where it is widely available through Japanese retailers and has collaborated with various Japanese stores.

Why it matters

bagjack is a rare example of a European accessories brand that has kept manufacturing in house in a major city, and its links to ACRONYM place it at the centre of the technical outerwear and techwear scene.
