I have bought in my life more than 20 waist bags ranging from 10 to 40 euros.
This one here is the best for its price by far.
It has large compartments with two big and two small pockets, as well as some small internal ones.
It has very good materials and very good and large zippers, unlike others that you struggle to find.
The only "drawback" is that it looks somewhat bulky around the waist.

The only companies that have bags with multiple compartments are Polo and National Geographic. Since I had a National Geographic bag, I decided to try the Polo one and I am completely satisfied with both the quality and the construction. I highly recommend it.

It is a very nice bag that I use daily without any problem. I don't have it in the middle but I wear it crossbody

It is quite large. Suitable for travel use. I put a regular wallet inside for coins, tickets, and a couple more folders comfortably.... Mobile phone and charger, Bluetooth headphones with their case, of course a marker pen and a multitool for car keys, home and vacation with their keychains, and at some point on the boat I put my wife's wallet and mobile phone. It was packed.
