Castelli Men's Prologo VI Jersey

Mfg PartNum:
In Stock Now
Ships Free!
Please Confirm Color/Size

Italian for "prologue", Castelli's Prologo jersey brings a lot of tech along for the ride. Now in its sixth iteration, the Prologo utilizes bioceramic nanoparticles in the fabric which keeps your winterized skin safe from the hot sun while the wrap-around side panels help ventilate the jersey from the sides and back while keeping a wind resistant barrier out front. With a drop tail design that allows for proper positioning of generous back pockets and a full length zipper, this jersey is the perfect warm up for what is surely going to be a hot season.

Note: Castelli apparel is designed with a performance cut that often runs smaller than that of other manufacturers. Consider sizing-up one size to ensure a comfortable fit — e.g., if you normally wear a Medium, select a Large in Castelli. Feel free to contact us with any questions or concerns.

Features & Specs:

  • New Punto fabric is light and breathable
  • Full length covered YKK® Vislon® zipper
  • Drop tail design with 3 large pockets in the rear
  • Reflective piping

Not as good as Prologo V

Lighter fabric which is ok. Sleeves not as tight as Prologo V but longer. Does not have the small zip up pocket in back for keys. Overall, I like the Prologo V better than the Prologo VI.

New iteration on the Castelli Prologo jersey

I have been wearing the prologo jersey for the last several years. It is a club fit, but runs small. I really like the longer sleeves and jersey on this latest version. I find it flaps around less at high speed and is more comfortable. These jerseys breath well. As with all Castelli products they run 1 to 2 sizes smaller than other brands.

Typical Castelli quality long sleeves

The overall quality of the jersey is good at the price point. I was hoping the Prologo VI jersey would have sleeve lengths similar to the Prologo V, but no. I guess I need to pay better attention to the pictures to realize which are normal bicep length and which ones are either to or past the elbow. I guess on cooler days the longer sleeves are a plus but otherwise they tend to bother me curling up around the elbow. Regardless I would however probably buy the gray one if I see it on sale.

Great jersey

The prologo Jersey usually seems a little too loose. Sized down for a tighter fit. Like the simple graphics. A good purchase.

Stylish & High Performance.

This is my fave all purpose top, from MTB to Road rides to Triathlon training rides. I appreciate the Castelli graphic design, sharp, stylish but never too flashy, trendy or obnoxious. This shirt is comfortable, breathes very well has excellent storage and length in the back and the sleeves are snug. Great Castelli Quality. On sizing I do need to size up a full size as they run small vs. US Men...IMHO.
