The Brompton Borough Waterproof Bag - Large is a robust companion that protects your things come hell and high water. Modelled after the Borough Roll-Top, it has a slightly smaller capacity but the huge added benefit of 100% waterproofing thanks to Radio-Frequency welded construction in place of traditional stitching.

A large messenger style bag with a roomy 25L capacity, the Borough Waterproof has a large main compartment lined with orange nylon to make it easy to locate essentials quickly. A padded laptop sleeve and zippered mesh internal pocket keep things organized, while the two roll-top pockets on the rear of the bag offer space for water bottles or wet gear. The roll top closure with squeeze-buckle closures keeps water out while allowing for flexibility when you need to carry a little extra, and the twist-valve expels air during compression for a compact svelte look. The aluminum slide clip connected to webbing on the front allows you to strap a helmet or raincoat to the outside of the bag. A reflective 3M patch on the front provides visibility on dark nights or in stormy commutes.
