All-discipline speed.

The Castelli Sanremo 3.2 Men's Speed Suit brings together the comfort and aerodynamics of a speed suit with the long-mile functionality of a traditional kit. While most speed suits are limited to short criterium and time trial applications, the Sanremo 3.2 extends its utility to almost any type of ride or race.

The top half of this dynamic duo is a jersey designed in the style of the Aero Race 5.1, which is constructed using Castelli's polyester Velocity Dry fabric. Velocity Dry features a tightly-woven construction to usher airflow over your body as you ride. As its name suggests, it also expertly manages moisture and creates a contoured, anatomic fit. Three rear pockets—something of an anomaly in the speedsuit world—provide valuable space for carrying spare tubes, a handful of snacks, and other ride necessities.

The bottom half of the suit is Castelli's popular Free Aero Race Short, which is designed for aerodynamic racing and comfort during long, back-to-back rides. Castelli starts with a blend of breathable, moisture-wicking materials when constructing the shorts, using its proprietary Forza fabric to achieve a contoured fit across the thigh panels of the shorts that will maintain gentle compression throughout hours spent pedaling in and out of the saddle. Dimpled Vortex fabric complements Forza facilitates more efficient aerodynamics on the wind-exposed areas of the shorts along the outer legs and lower back. The large leg cuffs are Giro Air, which is more mesh than elastic and allows for the same secure grip as elastic but with smoother, more evenly-distributed pressure on the skin.

Castelli lines the suit with its top-of-the-line Progetto X2 Air chamois, featuring a luxuriously soft arrangement of multi-density foam strategically placed to provide support on 100 mile road races or 60 minute crits alike without inhibiting your movement in the saddle. A four-way stretch outer layer with an anti-odor treatment and soft, micro-denier surface blends the chamois in with the rest of the shorts for a smooth, unified fit.

  • Show up to the start line in this proven road racing design
  • Next-to-skin fit optimized for your in-saddle body position
  • Supple Progetto X2 Air chamois provides hours of support
  • Reflective strips improve visibility on the roads
  • 3 rear pockets stash fuel for long races
  • Full-length top zip eases getting into and out of the suit

Just get it. Seriously.

  • Familiarity: I've used it several times
  • Fit: Runs small
  • Size Bought: XL

Buy it. It's bloody fantastic. Get it because:

You want something without straps.

You want something that's super lightweight.

You want something that breathes.

You want a one-piece that's actually practical

You want some self-control when it comes to buying gear and this will be the last thing you buy before for a while.

Light: great for warmer weather.

Snug: Close fit but in no way restrictive.

Butt-Friendly: I own more cycling gear than I could possibly need, including two other pairs of Castelli bib shorts with the Progetto X2 Air chamois - this chamois does the business yet feels way thinner than other pads.

Practical: The way the speedsuit unzips makes it easy for the bathroom etc.

Attractive: Looks great on the hanger - put me in it and it drops from a perfect 10 to well....

I'm doing my first century tomorrow and I'll be using the San Remo :)

Sizing: As it says below, I'm 5'10" and 180lbs. I used to be MUCH bigger which means I still have a gut and thighs like boxers' punch bags. Without those, I would have purchased a Large.

Just get it. Seriously.

Sanremo speedsuit

  • Fit: Runs small
  • Size Bought: Large

Great speedsuit! I definitely recommend this to anyone looking for a comfortable and aero suit. Size up. I typically wear a medium in castelli. Glad I got a large as it fits perfectly. I am 5'11", 175 lbs. This suit can also work for a tri suit. I plan to wear it for long course racing, anything half Ironman or longer.
