Castelli Mens Bodypaint 3.3 Long Sleeve TT Speedsuit

The Castelli Body Paint 3.3 Speed Suit LS is an exceptionally aerodynamic long-sleeve time-trial racing suit.Developed using CFD modelling, wind-tunnel testing and extensive professional racing experience, it was designed to reduce drag across the entire body and was positioned by Castelli as one of its fastest-ever commercially available speed suits.

Castelli’s Boundary Layer engineering uses strategically selected fabrics and surface textures across different parts of the suit to manage airflow. The shoulders and lower legs use specialised aerodynamic fabrics, while the very close Race Fit keeps the suit smooth against the body. A premium Progetto X Air Seamless cycling seat pad provides comfort during longer time trials.
