Hey All, getting ready for a trip to Tennessee and considering a 3/4 Helmet for protection.
I live in PA and rarely where my 1/2 helmet. I have a bad neck and don't want to waste the money if:

1. with the 3/4 shield will the air come up inside the shield ? and bang my head around ?

2018 Streetglide, no lowers or wind deflecting shields

 

Dude it depends what helmet there are a million diff ones

 

I have the HD 3/4 and have no issues with wind blowing my head around as long as the vent in the faring is open. But I do have lowers, Almost no wind hits my face with the shield down, so much that I raise it sometimes to get some breeze on my face.

Just an example

 

I've always preferred a 3/4 with full face shield. I wore a half helmet once and couldn't stand the way the wind would pull up on it and the strap would dig into my chin. I find the 3/4 very comfortable and love the full face protection from wind, sand and bugs. You can get the occasional dirt coming up from underneath but it's rare. It's cooler and less claustrophobic than a full face but so much more protection than a half.

As far as buffeting, that will depend on you and your bike. As mentioned, the vent should help but it all depends on your height vs your windshield. If your windshield deflects the wind across the top of your head instead of over it, your going to get buffeting. If you have a short or basically no windshield and the wind hits you directly in the face, the helmets are designed to be pretty aerodynamic so it should be good then. Preferably the wind is going well over your head. I ride a Road King with no lowers but I do have the fork baffle ( not the fangs ).

 

I have a Shoei RJ Air and a Nolan 3/4. No problems with either regarding buffeting. The Nolan has a full face shield and was great when I had a Sportster with no windshield, great protection from bug and debris. the RJ Air has no shield but I have a FLHTK now so the windshield is all I need. Never loved the 1/2 helmets, seemed to catch the wind more and pull. Plus the 3/4 cuts wind noise and I can still hear the stereo and the pipes just fine. Try them out in person and get one that fits your head right you won’t regret it.

 

I ride with a 3/4" (Bell Sena 9, IIRC), with face shield. The fairing and windshield keeps most of the airflow off of my face. Maybe couple times when I was riding fast, in very strong cross wind, some turbulence caught the face shield and tried to lift it. It was more annoying that anything, and only happened a couple times.

 

" no lowers or wind deflecting shields"
^^^ That ^^^ right there is a big factor in your decision, and may be unique with many commenters in the Touring Section.

 

What's wrong with you people? Don't you want to look good in the casket? Full Face or nothing!

 

I bought that helmet about three months ago, went from half helmet to that and I am seeing/hearing less road noise and not much air push on my head. Have worn it with and without the face shield, out yesterday in 97 degree weather and it breaths better than expected. I have not had a problem with wind coming up behind the shield and I usually put it up a little to allow air in.
