I'm reviving this thread with a question. I think I (finally) found the helmet I'm going to keep. I bought and returned a few during the holiday season. The one that's now sitting on my table seems very well ventilated. When I stand in front of the mirror, I can see light coming in through the vents. But that also means the sun will be coming in. I don't like direct sunlight. Even though I get warm pretty easily, I don't wear racer back jerseys and rarely go sleeveless. I like sun protection. Is this a concern with the wonderful ventilation?

I actually have two helmets here now. One is the well-ventilated road helmet, the other is a nice MTB helmet. Both good end of the year prices. Maybe I should just keep them both
