I first used the goggles in the sun and was very pleased. The ventilation is good and works for active "Schwitzern" ;-). The additional disc protects neatly from the sun and glare. If the weather turns, there is a bit impractical to take an extra slice. But everyone must decide for themselves. The problem with difusem light is, however, not at all solved. I've been wearing a pair of glasses with polarizing filter, which had significant improvements in visual result. This goggle has no such glass !! There is no difference between glasses and glasses. Unfortunately only rip. So who sends it to the polarizing filter and a better view at difusem light value, should look for a different spectacle. Anyone looking for a good spectacle for the Skialtag, will be satisfied.
