I have used Bandolier products for years. I particularly like the phone case with the side snap pocket. On my recent trip, using my credit cards in my Apple wallet, and 20€ in the snap pocket, I tap paid for almost everything, and I completely quit carrying my wallet, pocketing any coins received. The cases are a little expensive, but last a long time. I find that the pastel colors do show the dirt, so prefer the red and blues.
The company stands behind their product , and in one past event I had a problem, they shipped a replacement within 24 hrs.
The neck strap obviously prevents dropping your phone in a canal, or leaving it unattended while you eat.
I have found a small battery that fits perfectly in the snap pocket, and if I need to connect to the phone, the battery has a short built- in cable which connects while the battery stays in the pocket- so convenient! The battery is available from a different vendor.
Safe travels to all!
