A fresh take on the T Bag, the Borough L Roll Top is made using Brompton's exclusively developed 1000D Cordura Broken Twill fabric for superior durability and weather resistance. New features include an adjustable external load carry strap for easy access to helmets, jackets, or oversized items. There is large zipped pocket on the front for quick access to essential items, re-designed rear pockets with an integral water bottle sleeve, and a laptop sleeve.

The plastic handle has been replaced with a tactile rubberised webbing handle, which means this bag is compatible with all Brompton handlebar types.
