This was my first purchase from PacSafe and I have to say I am very pleased with the quality. The only reason I only gave this four stars is because it was too small to fit my headphone case, and overall it was a bit smaller than I expected. Yes, I did see the dimensions but I wanted to try it out anyway. When I got it, it was a really, really nice bag. It locked easily and I felt I could take it on a trip and not worry about anything getting stolen. I ended up getting a bigger bag from PacSafe and will review that later, but I am giving this one to my son who lives in NYC. I feel this is the perfect bag for him to have around town and while on the subway, as he can lock it up and know no one is going to take anything out of it without taking the whole bag. Overall, I do recommend this sling pack, but note it will hold a small firearm and a few other items but it will be packed to the brim.
