Dont see why one should be obliged to spend copious amounts of money for aero helmets when you can manufacture an adapter quite easily. Unfortunately the video is in Spanish, but not much was lost in the lack of translation.
Any Spanish speakers who'd be able to identify the type of plastic sheeting he uses?

Plastico

I can't imagine you would be allowed to race in it given it wouldn't meet Australian standards

Also goes against UCI rules.

Yip covers are not permitted

Also its not as effective as an aero helmet

Gee, it looks like 4 seconds over 40KM doesn't it?
