Sanremo 4.0 Speed Suit

The Sanremo 4.0 Speed Suit from Castelli 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 4.0 extends its utility to almost any type of training ride or race.

The top half of this dynamic duo is a jersey designed in the style of the Aero Race, which is constructed using Castelli's Velocity Rev2 fabric. Velocity Rev2 features a tightly-woven construction to usher airflow over your body as you ride. It's extremely comfortable since the body fabrics will keep you dryer and cooler than the simple Lycra utilized in most skinsuits. Two rear pockets, something of an anomaly in the speedsuit world, provide valuable space for carrying spare tubes, a handful of gels, and other ride necessities.

The bottom half of the suit is Castelli's popular Free Aero Race 4 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 Giro4, which offer a smoother, more evenly-distributed pressure over 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.

  • A proven road racing speed suit design for an aero edge

This is my 2nd Castelli skinsuit. I am 5'6" but I am not skinny. I bought large and it fits well (snug) but difficult to take off when pulling out of the sleeves. I like that I do not have to worry about jerseys bunching up. I use the back pocket for my cell phone while riding. I also sometimes stuff a GoPro in the back pocket also.

I've had the previous version of these suits and they were also fantastic. I used a Large in those and while they felt good for the initial try on, I had wished I went with a medium. I'm 5' 11", 152 pounds, so lanky but above average height. Fitting me is tough, either I have to fit my height or my skinny, both is a rarity. I went with a medium in this suit and it is a snug fit but totally fine. Very minimal bunching and they made the sleeves longer, much appreciated. Now I won't have two goofy tan lines. Totally important. Pad is awesome, same as the other but has some different patterns printed on it. It appears to be the same to me. Full zipper is great, easy to use one handed, no issues. Great suit. Expensive but I like having to wash one thing instead of two (or remembering 2 things vs 1 for rides), so I'm good with it.

What is the longest ride you feel comfortable using these for?

Spot on review. I've ridden a ton of miles in these suits. I'm 5'10" and 150 and also have the medium. Fits like a second skin, but not tight anywhere, just comfortably snug... as aero clothing should fit. Regarding the below question, I've ridden plenty of centuries in these... the suit won't be the limiter of your ride distance.

I’ve never owned a skin suit. I’m 6’1” and 167 pounds. What size would you recommend based on my build? Thanks!

Hello Alex, Skinsuits can be difficult to size as you not only need to incorporate your torso length but chest size as well. Based on the information you have provided I would say a large would be the size you need.
