I have been buying leg bags like this for 15 years. This was the worst.
1. The material of the waist and leg strap is so smooth that it easily loosens.
2. The waist clip, instead of fastening in the front, on the waist or near the bag, fastens on the opposite side from where the bag is located.
3. When you wear it, it is impossible to put your hand in and take something from the first zipper (the tall one on top) because they haven't accounted for leaving a few extra centimeters of fabric for your hand to fit. To take something from this pocket, you have to take it out.
4. The main clip, under the logo, is on the inside part of the "tongue" and it is difficult to open it with one hand. In all the other leg bags I had, it was on top, and now I understand the reason.
In short, I will give it away and buy another one.
