Carry More. Ride Free.

The large Navy Borough Bag is Brompton's largest Waterproof bag, offering ample space for carry in all seasons.

The Borough Waterproof Large is the largest bag in Brompton’s range of waterproof bags. Completely impervious to water, the Borough roll top bag provides a large flexible carrying space, big enough for most journeys while providing weather protection in the meanest conditions.

The large Borough bag is made with robust materials and has a subtle two tone effect and multiple storage compartments help to keep you organized on the go; whatever your ride demands. Functional features include an adjustable external load carry strap – great for helmet or a jacket. The interior is finished in a bright orange lining and includes a laptop sleeve and multiple internal storage compartments to keep your valuables safe and organized. There are two large rear pockets which are both waterproof, great for a waterproof jacket, a water bottle or just keeping your soggy kit away from your lunch. The Borough bag is finished with aluminum hardware and features a rubberized webbing handle, making it compatible with all Brompton bike handlebar types.
