Peace of Mind
I really wanted a sling pack for my last international trip, and I really loved the safety feature of cut proof material and the ability to lock the zippers closed even though it took a little work to get it open sometimes (just me getting used to the way it works)...the cut proof strap gave me a peace of mind and the passport pocket on the back was great. Ultimately, it did what I needed/wanted it for and held all the little things I needed for the day. The only thing I decided I needed/wanted from it was a little pocket on the inside front of the pack to hold my credit card or some cash. I felt like the pocket in the back (because I had so much stuff in it) was inconvenient for my cash or card and rummaging around in the back deep pocket made me worried about my little wallet falling out (until I connected it to the key clip). It would have been a nice addition but it's absolutely more preference than necessity.
