Slicker than skin.

Castelli has incorporated extensive rider-feedback from the likes of Team Garmin-Sharp to hone the precise cut, shape, and elasticity of the Body Paint 3.0 Speed Suit. The result is a speedsuit that has been methodically tuned for real world race success.

Rider speed is all about managing airflow. To eliminate drag, the Body Paint 3.0 Speed Suit features a virtually zero-seam design using a low-profile, compacted thread Body Paint Lycra. Turbulent air is controlled as it comes off the helmet and front of the bike, by remaining close to the body, producing a managed airflow that ultimately reduces drag. Castelli claims that this suit will save you 12 watts over 40 kilometers compared to its closest rival.

The Body Paint 3.0 features mesh zones on the back and upper arms to aid in cooling and thermo-regulation. The fit and position of the arms is secured by a comfortable loop system at the thumb webbing. Because the Speed Suit isn’t intended for base miles, Castelli has kept a back flap to pin your number.

Finally, the Speed Suit features Castelli's most innovative chamois, the Progetto X2 Air. The skin-care layer of the Progetto conforms to the body without folding by using a seamless bacteriostatic fabric, which ensures airflow and assists in evaporation. The second layer is built with multi-density foam with varying thickness to ensure you get support where you need it most. Castelli’s Viscous inserts (a perforated padding added to the sensitive ishial and perineum pressure regions) provides additional comfort.

Will there be an xs coming in stock any time soon?

This thing is sweet, feels fast, tight

  • Familiarity: I've put it through the wringer

Bought this in a small. Im 5'7 , 139lbs during season. Medium build i guess for background. With a 34" chest.

I considered buying this for time trials. I also own a Assos cS.Uno Skinsuit . The castelli piece is tighter than the assos skin suit for sure. Both hunch you over while standing which is neat. Meant for time trial position not walking around. The castelli piece also has mesh on the back which i noticed is really awesome and wards off thermal stress. I rode the castelli in training on a 58F deg day and was legitimately feeling 'chilly'.

I don't have any data to support how fast this skin suit is, but i FEEL fast while wearing this thing....and feeling fast is part of being fast. I won the first time trial i rode with this. So it worked, duh. Will be keeping this piece for a long time!
