When looking for a Cyber Monday deal, you may come across something that we have not only tested but can back up with solid evidence, and this is one of 1 such examples. 

On May 5, my esteemed colleague Tom and I took all of the fastest helmets on the market to the wind tunnel to see which were the fastest on the day of empirical testing. 

The winner- if you ignore the poc Procen air, I decided to be just a time trial helmet with delusions of grandeur- was a specialty S-Works Evade3. 

Fortunately, there has been a significant 40% reduction in Sigma Sports in the UK. For how long we can not be sure. 

How fast is that"Well, it saves you almost four full watts at a normal riding speed - 30 km/h - the slowest helmet in our test It is also quite airy, as outlined in my Professional Avoidance III Helmet review which received a full 5 stars

In fact, this is the helmet I use when I'm racing, and it doesn't matter whether it's hot or cold, wet or dry.
