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.

All front luggage, except the Folding Basket, Mini O Bag and O Bag, comes supplied with a high-visibility rain resistant cover; secured to luggage using an elasticated hem, its sealed seams help keep luggage dry in heavy rain, and it takes up no room when folded.
N.B. The lower handlebars limit the front luggage options on an S Type: the C Bag, T Bag and Folding Basket cannot be used with the S Type's lower profile.
