The belt is very light, is completely forgotten in jogging, even without the need to tighten the pocket, extensible and my Oneplus returns there without any problems.
The construction and finish are very good, and the materials seem to be of good quality including the zipper.
Perfection would have been achieved if the inside of the zipper had been protected (although it does not seem aggressive suddenly I prefer to put the screen in front of me), and an elastic band had been scheduled to hold the key attached to the outer ring.
In short, a Spibelt for third the price ....
