Im also thinking about getting these... hopefully you've found an answer in the past few months, haha, but POC makes a pink lens for the lobe, and you can find extra lenses on backcountry.com. If they're out of stock there, Im sure you could have a shop order them in.
My question is, do these goggle fog up as much as some people say they do? Ive been reading some reviews; some say they fog every 30 seconds, some say never. The ones that said they fog up say its because the lens is over the frame... but thats also true with the I/O, which I have been using for 2 years and they rarely fog... So I'm wondering how there could be such a difference in performance with such similar construction.
