I just wanted to provide an update for those of you who read this blog post from a few weeks back talking about the new Oakley Split Jacket range.
For those of you unfamiliar they are a smaller version of the Jawbone, but with the same switchlock technology.
I have now seen that you can get spare lenses from the Oakley website (included vented/drilled for cycling) and that the custom website will let you design your own.
