We love sunglasses. In fact, our chief editor is a self-proclaimed sunglass hoarder. Walk into AG HQ, and you will see rows of sunglasses (all mostly from the chief editor’s personal collection). So when Rudy Project sent us their Agon, you know that he grabbed them for most of the testing. For those who are curious, Rudy Project chose the name Agon after the ancient Greek term used to indicate the “spirit of competition”.

The Agon is Rudy Project’s cycling-specific model designed around their new Integrated Vent Controller (IVC). The IVC, combined with Rudy Project’s Quick Change lens system, lets you choose between two difference lens positions—open or closed (or “off” and “on”). The open or “on” position allows for extra ventilation, while the closed or “off” position prevents water and debris from getting through. So, how does this work? Each of the Agon lenses features a built-in vent, and the frames themselves allow you to position the lens in one of two positions. Check out the images below to get a better understanding of what we mean.

We spent most of our time with the lenses in the on position to see how the Agon’s held up to South Florida heat and humidity. We never had any issues with fogging throughout our testing and felt the extra bit of ventilation over our face (as compared to when we rode with them with the lenses in the off position). In the on position, not only is the vent opened, but the gap between the lens and frame on the far end of the lens is noticeably larger too. This is something we appreciated on the hottest of rides.

The Agons also include adjustable temple tips and an ErgoIV adjustable nose piece. Combined, these two technologies allowed us to position the Agons perfectly for our face. This was also a benefit when switching between helmets as we could adjust the temple tips based on how the helmet fit over our head and ears.

Our only knock against the Agons was the lenses included with our test sample. Rudy Project offers lenses built from ImpactX – their shatter-proof and photochromic lens that they guaranteed unbreakable for life. Unfortunately, we only got to test their standard multilaser red lenses. And while they were fine lenses, we hope to test out an ImpactX example next time. And to be honest, we are just not fans of red lenses. After all, they don’t match our AG kit!

Agons with standard frames retail for $249.99, while the ImpactX lenses up the price to $299.99. Either are worth considering, especially if you have issues with fogging or fitting glasses around your helmet straps or ear covers.
