There are a couple of old posts on Wiley X riding glasses but I thought I'd add in my recent experience with these.
I bought mine just yesterday (WXHDECH02) for $AU126 in Adelaide and must say that are awesome. The foam seal around the frame is low profile so it doesn't feel or look like i'm wearing goggles (which they are not, they're glasses).
Also, very impressed how effective it works by keeping the wind out from my eyes, keeping them from watering.
Highly recommend it - worth every dollar.
Thinking the frames would be a gimmick or not work as effectively as they do, I chose not to spend the extra $50-odd bucks on the transitional ones (where the lense darkens in bright ambiant light and goes clear in low-light/night). Now that I know how well they work, i wished I had paid the extra coin and gone for them.
Yeah got em from HH in the city. They had some cheaper brand there but I didn't like em. Too bulky and the seal didn't feel as good.
