Castelli Sanremo 3.2 Speed Suit - Men's

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, facilitating more efficient aerodynamics on the wind-exposed areas of the shorts along the outer legs and lower back. The large leg cuffs are backed by 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 long and short rides alike without inhibiting your movement in the saddle. A four-way stretch outer layer with a bacteriostatic treatment and soft, micro-denier surface blends the chamois in with the rest of the shorts for a smooth, unified fit.

Performance Orientated and Practical

  • Familiarity: I've put it through the wringer
  • Fit: True to size

What attracted me to this product was that it gives you the benefit of a skin suit with the day to day practicality of a regular jersey. I've been using this for the past 3 months now 2-4 x a week. Very sleek and comfortable. Haven't had any real issues with this yet. Only real complaint is that I wish the pockets were just a little bigger. Perhaps 2 medium pockets vs 3 small pockets to improve this design further? As far as actual performance goes, I'd say it cuts down most times by at least 30+ seconds when compared to a regular jersey, even when you're just casually riding. The chamois pad also lives up to the hype. Highly recommended if you see it on sale.

Extremely comfortable, seems well made

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

As a mountain biker, I'd generally be pretty hesitant to buy a skinsuit. Even wearing all lycra puts you in the minority on the local trails. But I needed something that was going to be comfortable for marathon racing and would hold spare bottles securely. I'd read a few reviews of the San Remo 3.2 that said it was good in both areas, so I gave it a shot since it was on sale and CC had an additional $50 off $250. Basically, in the end, the price of this thing ended up being the same as just a high-end pair of Castelli bibs with the Progetto X2 Air chamois OR a top-of-the-line Castelli jersey. So it was worth a try.

I've worn this thing once so far, for a 4-hour trainer session. Yes, I felt silly, but I wanted to see how the thing felt for several hours in the saddle. It's phenomenally comfortable--yes, basically like a second skin. But it's extremely light and not at all restrictive (provided you get the right size--more on that below). The leg and arm grippers are very secure without feeling grabby, and the chamois seems to live up to the hype. Also, the one-piece construction is more comfortable than having bib straps over your shoulders, in my opinion. And the pockets will hold a bottle firmly in place, should you need that. You can also fully unzip it for some ventilation without the whole thing getting too loose. Again, I was on the trainer. But I don't think this would billow in the breeze if unzipped out on the road.

Now, sizing. As usual with Castelli, most people will probably want to size up. My vital stats are above. I also have a 31" waist and 39" chest, and--while slight by most standards--have maybe a little more muscularity than your prototypical cyclist physique. So there's really no world in which I should wear a Large and look for it to be skin-tight. But that's the deal here. Unless you are VERY lean, you'll probably want to size up, too.

In the end, this is probably going to get worn more than I originally planned, just because it's so comfortable. A really great piece of kit that's a great deal if you score it at CC's sale price.

I have had 2 SanRemo speed suits and every time I wear them, it reaffirms my love for this piece. It fits tight to the body, but it is not restrictive in any area of the body. I sometimes struggle with constrictive issues with bibs and shorts around the stomach, and the SanRemo solve that issue with out a doubt. This skin suit is not an ordinary one, Castelli basically takes a pair of shorts and a Jersey, sews them together so you get the same security of a bib, but without the straps. It has 3 full pockets on the back and zips all the way down like a traditional jersey. The backside of the Jersey portion is all mesh so there is no worry of over heating even on the hottest of days. Whether you are racing, or going for a long ride, this is always my kit of choice.

What's the UPF rating/ UV resistance of the upper material? Skinsuits are often very transparent material.

Hey Heath,

I doubt that this piece has any sort of UPF rating, at least on the back, because it is completely mesh. On the front, it has a traditional lightweight lycra, but I don't believe it has much of protection from the sun. When I wear this skin suit a lot, I tend to get a tan line of the tag on my lower neck/upper back.

Let me know if you have any other questions.
