Giovanni Rey (UCI pro) vs TJ Mathieson (UCI pro, US National Team)
These are a good option.
sigh...I'm chatty today.
BMX/Skate helmets are a good choice. They are light, inexpensive, and easy to find. A big plus is that they are rated for 3 crashes (meaning discard it after the 3rd crash) whereas normal road helmets are rated for only 1. Accidents happen. With a normal bike helmet, even if you hit lightly, it is suggested that you trash the helmet.
The downside is that they can get warm.
