We recently took a cruise from Barcelona to Lisbon. On one of the days we called at the port of Tangier in Morocco. My wife and I went with some friends we met on the cruise on a cruise sponsored shore excursion that included an afternoon in Tangier's busting Medina (market). Having been to the Grand Bazaar in Istanbul, we knew what to expect and being Americans we stick out from the crowd. It's still an exhilarating experience despite being rife with challenges (one couple we met were mugged for following the wrong guy down an alleyway). Back to the PacSafe EXP35. That whole day the bag was on my back and all zippers were set without any additional locks to tie down. As we walked through crowds, and in one case a faster walking gathering of men in their 20s came up from behind, I could feel tugs on the zippers like scavenger fish tugging on the flesh of a dead fish. I would turn around and(not the smallest guy on the planet) and they would break eye contact and fall away. Had I used my old traditional back pack they could potentially have grabbed my wallet, MacBook, or iPad, the latter two I hardly ever leave back on the ship. This bag is awesome. There is no other word to describe it. The locals met there match with PacSafe.
