The Brompton Borough Waterproof Bag - Small is a robust companion that protects your essentials come hell and high water. It can be worn as a backpack or messenger bag thanks to its one-handed latch clip. The roll top closure with daisy-chain 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 waterproof Aquaguard zippered front pocket offers just enough space for quick-stash items like a phone, keys, wallet or metro pass.
Constructed from 600D TPU-coated polyester and made using Radio Frequency Welding instead of stitching, this bag is 100% waterproofed. Black aluminum buckles are rust-proof and will stand the test of time. A reflective 3M patch on the front provides visibility on dark nights or in stormy commutes.

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.
