Castelli Aero Race 6.0 Jersey

Tell us what the product is for

This is a high quality performance jersey for road racing, with impressive breathability.

Castelli says, "The first aero race jersey project was called split second and back in 2006, everyone thought Castelli was crazy. Back then, aero was only for TTs. Performance clothing meant moisture management. And you could win the Tour de France with a baggy jersey that was little more than a polyester T-shirt. Even Castelli's aerodynamic consultants expected limited gains, so they named the jersey Split Second, though, like now, they thought even small gains were worth pursuing. In the end, the gains were pretty substantial, and Castelli completely revolutionized the look of the pro peloton.

"Castelli is now on the sixth major revision of there aero jersey. Each generation has become more aero and better fitting. The Aero Race 6.0 benefits heavily from CFD analysis of wake flow in the riding position for fabric and seam placement. It also benefits from Team Sky riders' feedback, as Castelli have worked to make the jersey comfortable for their long hours of training and then racing in every possible weather condition.

"It's Castelli's most aero and most comfortable Aero Race Jersey yet. But they're already working on an update."

Reflective piping

18°-32°C / 65°-90°F

Very well made with quality stitching throughout combined with good material choices.

Performance is excellent, staying cool while you (allegedly) cut through the air more easily.

This isn't likely to survive a 20m skid down the road, but for general use it's likely to last a long time.

Excellent fit thanks to the amount of stretch in the material, so it will sit nicely regardless of any lumps and bumps you may have.

Fit exactly as an Italian medium should.

The comfort is really helped by the impressive wicking and breathability, so even when you're putting a real effort in you stay cool.

It's a high-performance jersey that comes with a high-performance price, but given that you can spend a lot more money and get a comparable performance it's not bad value.

How easy is the product to care for? How did it respond to being washed?

Very easy, simply washed it at 30 and stuck it on the washing line without any issues.

Could do with a zippable valuables pocket.

How does the price compare to that of similar products in the market, including ones recently tested on road.cc?

You could compare it to the Neon Velo Pro Fit Aero Jersey which comes in at £10 more and promises the same kind of aero and breathability qualities. Stu tested out the dhb Aeron Lab Raceline Short Sleeve Jersey which is the same price and may offer slightly more breathability but perhaps fewer technical features.

Use this box to explain your overall score

A very high-quality aero jersey that also offers impressive breathability. I couldn't test its aerodynamics, but everything else is exactly what you want from a high-performance jersey.
