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 organised. 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 aluminium hardware and features a rubberised webbing handle, making it compatible with all Brompton bike handlebar types.
