Versatile sport sunglasses
Running: I use them in combination with earphones (see the picture). They hold really well and again - I remember about them only when I need to wipe out sweat. Great feeling during 30km+ runs, and also in speedy intervals and strides. They hold really well and do not cause any discomfort. Funny is that with blue glasses I cannot see anything on the iphone screen, so polarisation is apparently there. I don’t look at the phone screen when I run, so not an issue for me.
