@dan is right. I know it's a huge wad of cash to spend on plastic, but Radars are just great. Mine have never fogged-up, even when riding in ~35c temps and just stay put, which is important for me as I'm more of a runner these days. I've had my pair for about 4 years now, my 1 year old had nicked them a few times and they're still scratch-free and look like new.
