Batoh Ergon BA3

I am selling an Ergon BA3 backpack with a spine protector, a SOURCE water tank and a raincoat. The backpack is in good condition and, compared to the standard one, I had a helmet attachment added to it (see photo). The backpack has height-adjustable shoulder straps, and by opening the extension, its content can be increased by approx. 2 liters (15 + 2 liters in total). For the backpack, I bought a SOURCE reservoir reservoir. I put only clean water in the reservoir.

The backpack is black, the different colors are made by the materials used only in the photos.
