Oakley fast jacket XL... also interchangeable and they stay PUT without being uncomfortable. I have some bolle transitional sunglasses for night riding (they go from clear to a modest tint) and they're not as good.
I wish I had a vented pair for cool days in the mountains, they get a little steamy when I'm huffing and puffing up the hill. Some day I'll get some jawbones or whatever they're calling them now.
