Castelli Sanremo 4.1 Speed Suit – Ineos Grenadiers

Ineos Grenadiers’ Castelli Sanremo 4.1 Speed suit has a front opening that is the most noticeable unique feature, but Castelli have worked on every other detail to make it the perfect racing suit. Aerodynamic thanks to CFD-based seams and wind-tunnel-selected fabrics. It’s comfortable thanks to a body fabric that keeps you drier and cooler than the solid color his Lycra® fabric that other companies use.

The bottom part of the suit is Castelli Free Aero Race 4 Bib Short, which is the most comfortable suit for even the longest, toughest race days. As well as new fabric and seam placement, the pockets have also been improved for racing. It’s slightly narrower for better aerodynamics, but now has two large pockets instead of three smaller pockets for easier access during the race.
