Well-made and secure, but not quite perfect
The bag is exactly as described, and seems to be well made and certainly secure. The chest strap and 2 good-sized bottle/side pockets are what persuaded me to purchase this instead of the X 20L, but the Vibe really needs a small additional externally accessible compartment - somewhere to leave glasses, charging cables, tickets etc, without needing to unlock and open the main compartments.
I'm looking forward to 3 months on the road with this bag around Europe.
