All of the Rosso Corsa experience and knowledge gained from the road and applied it to the gravel surface. Castelli optimized Castelli's Sanremo S Speed Suit by adding nutrition pockets on the central quad position on the leg to allow quick, easy access to gels and bars.

Placed on the front, even full pockets will not increase aero drag like side pockets, and the contents won't bounce as much. they applied the hydration pouch from Castelli's Unlimited Pro 2 Jersey to keep the hydration bladder stored safely and securely. Feed zones in gravel racing have become increasingly risky and stressful, but with this speed suit you should be able to fly right through them. The jersey fabric gives UPF 30 protection to block 97% of UV rays for your longest races.

Feedback from Castelli's Castelli SOG athletes was instrumental in the development of the Unlimited Speed Suit, making sure it serves the needs of a modern-day gravel rider, whatever the distance you choose to compete in.
