Messenger bags are great, but with two straps to distribute the load, a backpack is often a more comfortable option for longer rides or heavier loads. Unfortunately your options have either been student backpacks that leak like a sieve, sit up too high, or cost a fortune. We designed our cycling-specific backpack with a full welded waterproof liner that is removable and replaceable if it is punctured. 1500 cubic inches. Bike commuters have long -respected the combination of value and performance the Banjo Brothers Cycling Backpack offers. Fits a wide range of riders. Unisex design. Fits female riders 5' 2" and up. For female riders who need a smaller pack, check out the Banjo Brothers Metro Backpack.
