Very practical it allows me to put in my important papers (passports returned it) or my phone. The largest of these pockets can even host a large 5-inch smartphone types. It's good to have because it limits the risk of pickpockets of aggression as one feels on the skin (even if it is forgotten) it realizes if someone tries to steal it.
The grip is slightly elastic and can tighten, so I have no feeling of embarrassment when I use it.
Last very valuable point it passes easily to the machine. As I wear it directly on your stomach gets dirty despite the breathable fabric.
