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

Robust materials with 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 interiors are 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 rain jacket, a water bottle or just keeping your change of clothes away from your lunch. This bag is finished with aluminium hardware and features a rubberized webbing handle, making it compatible with ALL Brompton handlebar types.
