The first backpack designed to work with the Brompton front luggage system, leaving you with free hands for your bike and anything else during your commute. Made from a recycled polyester yarn, with a padded air mesh rear panel. This bag features two expandable side pockets and a smart magnetic snap system to keep straps safely in place whilst riding. An ideal bag for journeys that include a number of off bike sections or for those that prefer to spread the load across two shoulders.
