Castelli Sanremo BTW Speedsuit

Part of Soudal Quick-Step's official team kit, the Sanremo BTW Speed Suit has been developed over the course of a decade, both in the wind tunnel and on the roads of the WorldTour, to pair the aerodynamic advantages of a TT suit with the comfort required for road riding.

Its aerodynamic capabilities are delivered by CFD-based fabric placement and seam construction, airflow shoulder construction, elbow length sleeves with raw-cut edges and the use of slippery yet breathable fabric.

The suit's comfort level, meanwhile, is elevated by minimal seams in the shorts, the inclusion of Casatelli's premium, cushiony Progetto X Seamless Seat Pad, and the fact that the jersey and short portions remain separate at the front, making for easier comfort breaks. The jersey portion moreover unzips fully, allowing easier and faster cooling on the move.

Finally, this race fit speed suit contains eco-friendly, bluesign approved fabrics, allowing you to benefit from the aerodynamics, comfort and efficient moisture management enjoyed by the pros with a clear conscience.

Already engineered for optimum aero efficiency at speeds of 0 to 55km/h, up to a 6% aerodynamic advantage is added by donning the Bolero SS or Bolero SS Base Layer underneath it.
