I use the MetroSafe 200 Shoulder Bag to carry my&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/camera/dp/B0001EY1GY/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">camera</a>&nbsp;and its accessories, plus a few other odds and ends. Overall, this bag is a fine way to help keep valuable stuff secure while traveling.

Things I like:
*The bag does not look like a typical laptop or camera bag.
*Both the strap and the bag itself are reinforced with metal cables or mesh, providing good protection against slashers and cutters.
*The internal pocket zippers can be immobilized by attaching them to a metal hook inside the bag.
*A "turn and lock" strap hook allows the bag to be attached securely to chairs, luggage racks, and other large objects.
*There is a good selection of pockets and pouches, with varying levels of accessibility.

Things I don't like:
*All the metal reinforcement makes the bag and strap a bit stiff and inflexible. This makes it difficult to squish or fold the bag when packing it inside of another piece of luggage.
*The strap does not have a sliding shoulder pad.
*Unless you carry small and slender water bottles (say, the size of a Red Bull can), the external bottle pockets are not large enough to be useful. I use Nalgene 1L/32oz wide mouth bottles and the pockets cannot accomodate them even when fully expanded.
*The paint on the lockable strap hook quickly wears off from rubbing against the metal loop it attaches to, leaving the hook without a protective finish.

Bottom line: despite some minor design flaws, the MetroSafe 200 is well constructed and provides good protection for valuable items.
