    • Castelli Sanremo 4.0 Speed Suit SS20

  • Castelli Sanremo 4.0 Speed Suit

    Take your race performance to the next level with Castelli's incredible Sanremo 4.0 Speed Suit. Honed via Computational fluid dynamics (CFD), wind-tunnel testing and real-world testing, it's the winning edge you need in the rush for the finish line.

    Cycling Fast Needn't be a Drag

    Combining shorts and jersey into a seamless one-piece unit may not appear significant but the aerodynamic gains are in fact considerable. Castelli uses Vortex fabric on the legs and Airflow shoulder construction to minimise drag while seams are carefully positioned so as not to disrupt smooth aerodynamics. The suit is also cut to fit beautifully when you're in a low riding position -  at thirty to fifty kilometres an hour, it's frighteningly efficient through the air. This latest fourth-generation suit retains the front opening design to make it just as convenient to wear as separate shorts and jersey too.

    Uncompromised Comfort

    While designed for pure racing speed, comfort hasn't been compromised. The upper provides the support for the shorts, removing the need for bib straps and so enhancing the breathability of the suit. As you build up speed, and as a consequence, you start to sweat, the functional fabrics are quick to move it off the skin for greater comfort. 3D mesh fabrics also allow greater ventilation, the extra airflow speeding up the cooling effect of sweat evaporation. Lastly, wide GIRO4 leg grippers provide a seamless and smooth transition between suit and skin. 

    Progetto X2 Air Seamless Seat Pad

    Let's look at the Progetto X2 Air Seamless seat pad in more detail and see just why it's so incredibly comfortable. The first contact point against the skin, the upper skin-care material, is now seamless and even softer than previous versions letting you enjoy smooth and chafe-free pedalling. The next layer, Castelli’s infinitely variable thickness padding, imparts just the right level of support where you need it, thicker under the sit bones and thinner on the sides and under the perineum - the result is intense comfort with reduced bulk. 

    Lastly, to really push home superior comfort levels, perforated viscous padding is added under the highly sensitive ischial and perineum pressure areas, offering luxurious support when you're on the saddle for hours on end.
