Perfectly safe in every way.
I have MS which has meant that I recently have started to need to crutches and a mobility scooter to get around. I also travel a lot. With the crutches, I am very easy prey for pickpockets. The Pacsafe features give me the confidence that my stuff will be safe. On top of all the details listed on the website, the size is perfect for phone, wallet, passport, etc as well as a small waterbottle. The double ended main zip means it's very easy to close. The strap allows the bag to be slid over your shoulder without snagging on clothes and the large tabs on the zippers make them easy to use when my fingers are clumsy and numb. The bag opens up quite wide is it's easy to see what you have inside. It also closes pretty flat as it rarely gets in the way when I'm using my crutches. When I'm on my scooter, I rest the bag on my knees and it has yet to slide off them, even when I do a sharp turn (!)
