Still the fastest thing for road racing, but now even faster. The Castelli 3.0 Sanremo speedsuit is just what you want when the pace is high! The speedsuit also features a full length front zip allowing as much ventilation as you want. The upper part of this suit uses the technology from the Aero Race 5.0 jersey design, which is the most aero jersey Castelli have ever made. It features the Velocity Dry fabric which means that it dries almost instantly. 3D fabric can be found on the back and sleeves for a silky smooth feeling on the skin.
