I've been wearing them once an hour during training today for the first. The glasses are super tight, no water or similar flows. That's a big plus. She sits very pleasant, but the field of view is quite limited. In addition, the "anti-fog" does not exist. They fogged immediately, after a few minutes. I've already returned.
Conclusion: Not even.
Property me now Speedo Speed Socket fetched. Which is not only of the packaging before quality, but also on the seat strength. Was not yet with her in the water, but dry it already feels super vs. the ispeed. costs a 26, but 100% quality and a competitive spectacle!
