I have not been able to use this yet because of the quarantine, but I can tell that it is very great quality and sturdy. This will get lots of use!
Eash and quick to attach and detach and I put a passport and small stuff in a pocket of the belt. I love the pockets of it.
It really helped me to London trip for 5 days. It makes the pack even lighter and feels much better carrying the Bamian Pack.
