Brompton Borough Waterproof Bag - Small


A 'bar bag from Brompton, the smaller of the two Borough waterproof bags is compatible with all handlebar types, that's S, M and H. It's 9-litre capacity is perfect for lugging around some daily essentials, all carefully cocooned in its waterproof bosom of course. When the situation demands it and you've got more items to carry, the Borough's air release valve helps reduce the bag's overall bulk. 

Included with the bag, and a feature easily overlooked, the detachable two-way strap turns the Borough into a natty messenger bag, shoulder bag or backpack in a trice. A further webbed carry handle offers another point to grab hold of the bag - not only that, it makes it easy to mount onto the headtube of your Brompton. Just remember, you'll need a front carrier block to do so.
