just got them with my airbrake goggles (along with dark grey). These lenses are really good so far, im very impressed with the look and performance. Im pretty stoked that i now have goggles and lenses that allow me to switch mid day. i havent used the lenses yet but i wear them round the house. ill post later skiing results.
I have them as an extra lens for my Wisdom Goggles. I haven't ever used them, but when looking through them to get a feel for what they do was what sold me. They are a very purpose built lens. Maximum contrast with minimal shading. They are amazing for seeing definition in snow.
