Simple and sturdy, especially the strap and buckle.
Somehow, it's water-resistant and not water-proof; no internal zipper except for the small hidden pocket to store some loose change or a bunch of keys.
Would have been better if a small carabiner keychain is provided inside the bag and another strips of velcro on the front for better closure when the load is minimal.

Talk about load, this messenger is a masochist; enjoyed being abuse. OK, I am no sadist but this bag is really cool!Rating: [5 of 5 Stars!]
