At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Good scores are more common than bad, because fortunately good products are more common than bad.

The Castelli Prologo V Jersey brings together great breathability, strong looks, and a comfortable fit to create a very good summer cycling top.

The Prologo is now in its fifth iteration, as you can probably tell from the V in the name. Castelli claims it's the closest to the fundamental ideals of what it wants a jersey to be, with the relatively broad claim of creating 'your favorite [sic] jersey' – a big claim. But does it live up to its reputation?

Breathability is one of the main selling points of the jersey, with Castelli giving it 4/5 on its breathability scale. Here I agree with the Italian company. It has a large mesh vent running down under the arms and across the back, and the rest of the jersey is made from Stratus+, a two-layer fabric that lets heat out really well. The highest temperature I used it in was around 25°C, and it coped admirably. I would happily use this during an Italian summer.

The latest Prologo is a strong, clean looking jersey, with the red version I tested a bright and easily seen primary colour that hasn't faded at all in the six or so washes I have put it through. There is also a smart black band under the pockets, which helps it to blend into black shorts – a clever touch. There is also a shadow logo on the front, which I think looks really classy and doesn't make you feel like a walking billboard. There is also the scorpion logo on the left sleeve and central rear pocket.

Fit isn't totally relaxed but not what I would describe as a racing cut: it doesn't make you look like a kid wearing their dad's jersey but it also has a bit of give for those of us who enjoy a pint now and then. Fit is certainly Italian, meaning the large I wore was good for me – I'm normally between a medium and large for UK or US brands. Arm length is about average and certainly not an 'aero reaching your elbow' job. I approve – I find that the tan lines created when flitting between regular and aero arms can take away from the pride of the ruler-straight tan line all(!) cyclists crave.

Other features on the jersey include a full length zipper, which helps with ventilation if you need it, and a zip garage at the top to prevent chafing. There is also a strong gripper on the hem, keeping everything in place throughout, regardless of whether I have anything in the three well-sized rear pockets or additional zipped key pocket. Stitching isn't flatlock, but I didn't find any kind of discomfort even on long, hot rides.

It comes with an RRP of £80, which is about what I'd expect for a well-specced and good looking jersey. People will always say that XYZ is too much, but in this case I would be happy to pay up to £100 for something that performs like this.

So is the Prologo V my 'new favorite (sic) jersey'? Possibly. I really like the subtle look, excellent ventilation and good fit, and Castelli has certainly put considerable thought into it. There isn't a whole lot not to like.

Verdict

A strong showing from the fifth generation of the Prologo jersey

road.cc test report

Make and model: Castelli Prologo V Jersey

Size tested: Large

Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

It's a semi-relaxed fit jersey with good moisture management.

Castelli says: 'We've kept the outstanding moisture management of the Stratus+ two-layer fabric and the relaxed Prologo fit, but we've updated the details, from the collar construction that protects your neck from the zipper to the embossed chest with the Castelli shadow logo. The design feels instantly classic, while the performance is distinctly modern'."
