I had it on all day and literally forgot I was wearing it. It's super light, has very low clearance over the top of my dome, and has great air circulation. The adjustments system on the Vapor is so quick and easy, you can ratchet it tighter with one hand while you're wearing it and not get your hair stuck in the system. I snugged mine down so tight it didn't budge. Even with it tight I had great circulation and didn't overheat. The chin strap is tight and easy to adjust. I can't speak to its longevity but one weekend at Red Rocks and I'm loving it. Despite the high price tag, I can honestly say I'm very impressed. This is definitely the Audi of helmets.
