Brompton Borough waterproof bag - small - navy / grey
This sometimes underestimated bag was originally introduced by Brompton in 2020 - a roll top, with full waterproof capability as an alternative to the now discontinued Ortlieb Mini-O bag
This is the second iteration - introduced with the G Line in 2024
The colour is a slightly different blue from the original, it has some grey and orange detailing and a removable logo - you can choose between G and Brompton logos (they are held on with Velcro)
The Brompton Borough mini waterproof roll top combines a flexible design that can worn as a shoulder bag or a backpack, with more than enough space for a day trip adventure
Made using Radio Frequency Welding, instead of stitching, making the bag completely impervious to water
