Make a statement.

Inspired by the towering mountain passes and dizzying switchbacks along Switzerland's awe-inspiring Flüela Pass, Castelli's RS Superleggera Jersey was designed as a lightweight, everyday jersey that inherits much of the same technology as Castelli's pro race jerseys. A few functional details added to the Superleggera make it suitable for training, but we can't help but feel that it's a race jersey at heart, ready to propel you up mountain passes and neighborhood climbs not unlike the high-speed car it happens to share a name with.

Castelli strove to make this jersey as light as possible while giving it enough versatility to avoid strictly being classified as a climber's jersey. To do this, Castelli constructed the body and sleeves with 50g/m2 Futura fabric, a barely-there, stretchy synthetic that adeptly draws moisture away from your body as you ride. We were also pleasantly surprised to find that it has a strikingly soft touch. A compression panel of Castelli's Stretch Woven fabric added to the bottom half of the jersey allows the Superleggera to follow your movements in the saddle without constriction. 3-D mesh fabric inserts at the back and side panels further add to the jersey's breathability, facilitating airflow as you tackle steep, slow ascents when the breeze stands still.

In pro race kit, details like a zippered security pocket, top zipper protection, and gripper elastic around the waist aren't essential, but Castelli adds these finishing touches to the Superleggera for comfort and convenience during everyday rides. No-sew seaming on the waist and sleeves creates clean, lie-flat cuffs that won't pinch or chafe, and the joints are bonded and reinforced to ensure they won't unravel after a single wash.

Despite these "training" details, the Superleggera is still a race cut jersey, so expect the same tailored, smaller-than-average fit you would from other Castelli gear. It's also got the Italian firm's signature in-saddle design: a tighter fit across the chest when standing that will feel normal once you're riding. A dropped back hem provides extra coverage and security, and reflective accents add visibility on dim descents and the days you stay out pedaling after sunset.

Part of Castelli's Rosso Corsa (race) line, if it fits you right (you gotta be pretty slim & fit)... this is a fantastic -and really good looking- warm weather SS jersey.

Made with a lot of attention to detail. Made in the USA (unusual for Castelli). Very fine design/quality.

Superlegerra means "superlight" in Italian. So the main textile used here is a very fine, light, soft lycra. Anyway, it is strikingly soft. And very breathable. With stealthy black mesh sides.

The material may be a little delicate -time will tell. I doubt this will be your workhorse summer jersey. Perhaps reserved for more special rides?

Fit: Classic Castelli (Italian) sizing. Size up +1 from your normal street size.

***Caveat: The "no sew" arm band is narrow and does not expand much. It will definitely cause constriction (and sausage arm) on guys with larger​ biceps. This particular Castelli jersey is definitely best suited for fit, slim to ave. riders.

It's a beautiful jersey. Super soft material, race cut, very sleek and professional looking.

I normally wear a medium, a large in Castelli, but I might wear an XL in this. No seams on the sleeves which was very cool but the fabric on the ends of the sleeves was tight and giving me sausage arms, so maybe the jersey is more for pure cyclists and not triathletes : ) Returning it but I wanted to highlight a review below that this product is made in the USA, which is very cool.

Runs VERY Small

  • Familiarity: I returned this product before using it
  • Fit: Runs small

This is a nice jersey. Unfortunately, it runs way smaller than even the normal Castelli's. I'm muscular and lean and wear an XL jersey for most brands and a XXL in Castelli. I recently purchased this jersey in a XXL and it was two sizes too small... at least. I couldn't even get my arm through. Very disappointing


  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small

This is one of the nicest jerseys that I've ever put my hands on. The fabric's feel is so much softer and smoother than anything else I've tried. Be warned that the fit is very, very race, though.
