I have the goggle strap for football, worried because my glasses in quick sprints like to adopted or disruptive rumhüpfte on the nose. The goggle strap fulfills his job 100% !!! The optics I think the necessary application as completely unimportant. Because it works perfectly. And with the price performance ratio, there are clearly 5 star. Thank You !!! Did I already ordered one also because of the price. You never know. So who needs persons thing, BUY !!!
