The Brompton Borough Roll Top Bag - Large is a fresh update on the hugely popular Brompton T-Bag with improved functionality and performance. It is a large messenger style bag with a massive 28L capacity, roll-top closure, water bottle pouch and impressive weather resistance. The largest bag Brompton makes, the Borough Roll Top Bag is perfect for bike packing, touring or just large grocery trips. Its durable construction and understated appearance makes this an ideal accessory for any Brompton rider wanting to carry that little bit more.
Constructed from heavy duty 1000D Cordura Broken Twill fabric for fantastic durability and weather resistance, the bag has an extra large main compartment with a large zippered inner pocket, two front zippered pockets, and two rear water bottle pockets. An easy access high visibility rain cover with a 3M reflective strip is also included for those unexpected rain showers which can also be used to make you more visible on the streets and keep the bag looking fresh.

Brompton is the only company we've seen that answers all three criteria - and believe us, we've tried every brand out there. The reason others can't compete is because Brompton has answered a fundamental engineering problem. If a bike is going to unfold to a large footprint (which takes the twitch out) then it is unfolding to a bigger bike - and by all logic, a bigger bike unfolded would be a bigger bike folded. So, it's pretty much true that for most folding bikes they either have great rideability but poor transportability or vice versa. And nearly all of them are a mess to fold.
Not Brompton. Brompton has designed the Platonic form of all folding bikes. The bike folds to the smallest size on the market, unfolds in a highly precise and easy manner, and has the same axle-to-axle footprint as a hybrid bike. How did they do this? By not only designing a clever frame, but also designing some 1200 proprietary parts that make everything fit - and fit perfectly. Oh, and nearly all of this is made in England. No wonder this bike has a cult following.
