When I think messenger bags, Berlin isn’t the first city in the world that comes to mind but Bagjack has been locally producing handmade messenger bags and accessories since 1993. Their 20 litre capacity Messenger NXL (Next Level) is a versatile bag that can be used as a messenger, a briefcase or a backpack (without having an additional bulky harness system). The bag can be closed using “traditional” velcro or should you need to silence it, their Fidlock magnetic hasp system. The NXL uses a splash shield with adjustable closure to keep out the weather and its interior can be customised using their modular and removable building block system.
The NXL isn’t a cheap messenger and prices start at €499 ($650US)
