When I went skiing last week, it was the first day with my oakley a-frames. I was wearing a bandana and they fogged up on the inside and I made the decision to wipe the inside of them.. then found out a couple days later that it actually ruins the goggles. I'm not really sure why they were fogging up, but I'm hoping i didn't just ruin my brand new pair of goggles. Can you guys give me some info on this and clarify some things? Thanks
