The space miracle for multi-day and transalpine tours: The BX4 Evo from Ergon shines with 30 liters of volume, a well-thought-out organization system, perfect ergonomics, and top carrying comfort even under maximum load. The precise adjustment to the rider's anatomy is a breeze thanks to the 5-way adjustable carrying system, the ingenious load compression principle "Adaptive Carrier System," and the "Ergonomic Pre-Shaped Fit" (removable back plate with 3 individually bendable aluminum rails). The wide hip belt can be quickly adjusted in 4 sizes using thumb loops, relieving the shoulders. The BX4 Evo is optimally ventilated at the contact points thanks to 3-D spacer mesh. The super practical front flap is designed to hold a helmet, wet clothing, etc. – when not in use, it can simply be folded away. The rain cover in the bottom pocket, space for a back protector, and HiLumen reflective inserts for added safety complete the features.
