Brompton bag made by Fairweather using Okayama's Kurashiki region from heavyweight No. 9 canvas - a cotton fabric known for its durability - and finished with a paraffin coating for water resistance. With use, the canvas softens gradually and develops its own character: wear marks, chalk traces, the quiet evidence of a bag that goes everywhere you do. Inside, a ripstop nylon lining laminated with a waterproof film keeps the main compartment well-protected from rain. The roll-top opening expands to meet whatever the day demands - a change of clothes, a detour to a favourite shop, groceries carried home without a second bag. Attachment is straightforward: the bag slides directly onto a front carrier block from above. A strap on the back panel can accommodate a stem bag or small additional pouch. When travelling by train with the Brompton folded, an optional shoulder strap keeps both hands free. A bag that works like a basket - and earns its place on the bike. Made in Japan. *Requires a front carrier block for attachment. Available without frame for those who already own a front carrier frame.
