The ZEPHYR by FERRINO is a 17 l backpack that can be extended up to 20 l. Multifunctional, it can accompany you in many sports, from trekking to running, also excellent on a mountain bike.
The ZEPHYR backpack is very breathable in the back area thanks to the mesh that embraces a flexible steel structure (Hollow Back System), which in turn distributes the weight load evenly.
