Appearance:
My initial skepticism about the appearance of the sports glasses is quickly dissipated when I first held her in his hands. Great design and fits comfortably on the head.
Comfort and Training:
The sports glasses will not slip and is very comfortable to wear during sports. The glasses fogged not even at high perspiration. The included interchangeable lenses have also been tested. I use the F - 16 originating mainly for jogging. The darkened glasses are perfect when the sun shines. But even if the sun decides not to show the yellow / orange lens greatly helps in contrast perception. Especially with runs in rather dark forest bumps are easier to see than without glasses. In addition, it protects even from annoying pests which a continuous fly into the eye.
Price-Performance:
One of the main points for me. You get here for relatively little money a really great product.
5 stars from me and a strong buy recommendation!
