The Ergon BX4 Evo 30l bike backpack is a space saver for multi-day and transalp tours. Thanks to the 5-way adjustable carrying system, the "Adaptive Carrier System" and "Ergonomic Pre-Shaped Fit" (removable back plate with 3 individually bendable aluminum rails), the backpack can be precisely adjusted to the driver's anatomy. The quadruple size adjustable (quick adjustment by thumb loops), wide waist belt distributes the load comfortably and relieves the shoulders.
Thus, the equipment is always transported close to the body and pendulum-free. The BX4 Evo is optimally ventilated at the contact surfaces thanks to the 3D spacer mesh.
The multi-functional front fl ap is used to carry a bicycle helmet, wet clothing or equipment - it can be folded in when it is not in use.
In addition, the optionally available Sport Camera Chest Mount can be attached to the BX4 Evo using attachment loops. Including rain cover in the bottom pocket. When driving in darkness, integrated HiLumen re fl ector inserts ensure greater safety.
