Our wind tunnel tests prove these two aero helmets are the fastest, and they've just had their prices slashed for Black Friday
Briefly

To avoid that we spent a lot of money on some commercial wind tunnel time and took all the best aero helmets on the market to determine the very best aerodynamic helmet.
With this data, we've been able to pretty objectively say that the POC Procen Air is the fastest helmet on the market, but as it is effectively a time trial helmet this isn't a huge surprise.
The fastest 'normal' helmet was the Specialized Evade 3, and was faster even than the Procen without a visor.
The good news is that we've found both of these helmets on offer for Black Friday, so the watts/$ ratio only gets better.
