The update of the best-selling Ergon backpack is now even more user-friendly. Perfect for enduro and all-mountain use. One for all - with the completely redesigned 4-way adjustable carrying system, the back length can easily be adjusted between sizes S to XL. Thanks to the "Adaptive Carrier System" load compression principle and flexible aluminium moulding rail, the rucksack can be adjusted even more precisely to the driver's anatomy. The hip belt can also be shortened as required.

The pockets are divided into a main compartment with 4 inside pockets, a separate bubble pocket, a front pocket with pocket for tools and pumps and a hip pocket. The extra compartment on the back of the BA3 offers space for back protection (BP100) and a drinking bladder (BH300).
