The vent is designed to let the air go up and around you, so when you close it you get more air on you. This is a good thing when it's hot out, so next time it's hot out try closing the vent! you will get more air on you and keep you a little cooler
I'll try it when it gets hot. Otherwise closed except for heavy rain.
You do realize your on a motorcycle right. How much rain is coming thru the vent, really??
I never close the vent, ever!
your right about that it will work better at speed to keep the rain off you if you leave the vent open because the vent was designed to flow the air up and away from the rider, closed the vent is like the original batwing and is less efficient putting more dirty air on the rider
was 19° when I left for a ride a few weeks back and I felt a lot more cold air hitting my chin and upper chest area with the vent closed than I did after I opened it
I rode in the rain for the first time last week. I closed the vent. The dash stayed dry, as did my helmet shield. I didn't really notice much more buffeting with it closed and my helmet on. I tried closing it once, right after I bought it, while not wearing my helmet and noticed a little more buffeting, but nothing real substantial. I'm sure I'll try it out some more, but like most things, it really about rider preference.
