Brompton Waterproof Backpack + Frame - Copper

Dual-Orientation Waterproof Backpack for Life On and Off the Bike The Borough Waterproof Backpack in Copper is built to switch between two jobs without missing a beat. Mounted to the Front Carrier Block, it rides in landscape orientation on your Brompton; lift it off and it rotates to portrait for wearing on your back. Weather doesn't factor into the decision either way, since the bag is made from a specially developed recycled fabric with a fully waterproof construction, so rain or a sudden downpour won't reach what's inside. Underneath the copper exterior sits a vibrant orange recycled nylon lining, a nod to Brompton's playful streak even in a genuinely functional bag. A roll-top opening with Velcro closure keeps the main compartment sealed, while an external zipped pocket (not waterproof) offers quick access to smaller items you don't want to dig for. At 17 liters, there's enough room for a day's essentials, and hi-density foam shoulder straps keep it comfortable to carry once you're off the bike. Made for the Ride and the Rest of the Day Dual-orientation design mounts horizontally on the bike and carries vertically as a backpack. Fully waterproof construction in recycled nylon with a TPU coating keeps contents dry in any weather. Roll-top opening with Velcro closure seals the main compartment against the elements. Concealed magnets secure the shoulder straps out of the way in seconds when it's time to ride. Hi-density foam shoulder straps stay comfortable whether you're commuting on foot or by bike. External zipped pocket keeps small essentials within easy reach (not waterproof). Two grab handles and an air release valve add practical touches for everyday handling. Vibrant orange recycled nylon lining and a 360° logo patch bring a distinct look inside and out. 17L capacity holds a day's worth of gear without adding bulk to the bike. Fits the Front Carrier Block on all non-electric Brompton bikes, including A Line, C Line Mk5/Mk6, P Line Mk1/Mk2, T Line, and G Line.
