This is a unique product that combines a smartphone shoulder bag with a bottle holder.
It is mainly worn for walks. It can hold a vertical 1-liter bottle, making it very efficient.
You can store a card case or simple small items in the back pocket.
However, it is not specially durable, so storing glasses, as shown on the manufacturer's site, is not recommended (they might break if compressed).
The drawback is that when used in a vertical position, the zipper opening faces downward, so if not properly stored, it may fall out when you take out your smartphone. It is not suitable for those who frequently take it out.
I used it for a while, but the fabric where the strap hooks on has torn. Rigidity
