This is my first adult helmet, a Schwinn Intercept.
Of all three of my bike helmets, it's the oldest and still gets worn the most.
-The full-face BMX bike helmet is the fastest, most aerodynamic and most effective of my helmets with the chin bar.
It's also the warmest.
-The three-dollar (Goodwill store bargain) roadie helmet is the coolest with the most vents, but I don't trust it's helmety/protective qualities.
There really isn't very much foam in it: So many vents.
Anyway, the cheap Schwinn "Intercept" being modeled by the shiny garden globe has been modified a little bit.
The stock plastic visor was removed and I added an air intake so that this helmet would work with my recumbent.
The paper mache intake scoop works extremely well:
-It moves a lot of air across my head and keeps sweat evaporated before it has a chance to form. Guaranteed cool head.
-It keeps the sun off of my scalp and forehead.

On the Sofrider, the smoothed airflow over the scoop and with no additional frontal area added to the helmet was win-win.
No speed penalty and yet vastly improved comfort.
On the Vendetta, this helmet keeps me cool enough to make enough power to keep going fast but it slows me down
about 2MPH on the top end. It's a good trade-off.
Test the effectiveness of ram-air on your own helmeted head.
You might be surprised how ineffective your roadie helmet is when it is on your recumbent.
