As another reviewer has described absolutely accurately, is the belt material of a flexible and highly stretchable and tearable band, which indeed is in itself a great thing. Unfortunately, the reflector strip is printed on the belt is completely inflexible! This means that once you've pulls a little bit on the belt, such as tears when adjusting the size or alone already by wearing the shoulder area, the reflector in countless small cracks apart and zerfleddern over time and will fall.
I do not understand how to apply rigid material on a flexible and stretchable substrate. This is an absolute bad design in my eyes.
I ordered the belt with the provider faguru, was supplied by Amazon.
The return costs in the amount of 3.50 to wear despite the way Amazon Prime membership itself.
I do not recommend the purchase.
