Brompton Borough Waterproof Bag - Large


Taking inspiration from the classic T Bag, the Brompton Borough Roll Top Bag brings an update to the roll top touring companion. A version of this bag first popped up on the Brompton Explore Edition so that should be a good gauge for what the intended use is - touring whatever terrain you come across.

The roll top design used on the Borough Roll Top Bag is a reliable way of keeping your kit dry. Inside the main compartment is a dedicated laptop space as well as plenty of room for changes of clothes, food, maps and anything else you might need on your weekend away. There are two side pockets, two rearward facing pockets and a zip-up drop in pocket on the front of the Brompton Borough. A clever addition to this Brompton Bag is the straps that stretch across the front - they can be used to carry a bulky piece of gear.

The Brompton Borough Roll Top Bag excels when you need to carry lots with you. Ample storage space and plenty of pockets for organising means you’ll be prepared for the week at work or the weekend in the countryside.
