Already last year I bought the sunglasses X-Loop. Unfortunately, I have the evening taken at the lake and forgotten about. The very next day she had already a new owner and I had to put on another pair of sunglasses. Since my glasses had very good though promised, I ordered another. This time, however, equal to more of it. At this price, you can slam quiet. Especially for beach volleyball is the spectacle of the hit. It keeps very well on the head and therefore falls on a flight in the sand not the same from the head. However, this good maintenance can create an oppressive feeling in the head, so I would prefer a different sunglasses here while reading in a deck chair or on the towel. With regard to the information provided by the UV protection I entrust the manufacturer, since I have no way to check this themselves.
Due to the low price and good support in sports, there are of me 5 stars!
