The Jiro Arrowhead and the Anti Fog Coating

Gustav uses like the giant TT helmet with glasses. It looks fine. And some other athletes too, just because generally glasses lenses will be more anti fog and come more comfortable than a helmet lens. But if you're going to do the sunglasses, I would maybe even get a different helmet than the jiro. You don't have to explain. Just go look at some pictures. The heat from my head dissipates quite well. When there's like so much moisture in the air, that's the problem with fogging.
