  • Castelli Sanremo 4.1 Cycling Speed Suit

    Retaining the same hyper-efficient design as it's predecessor, but with a few minor tweaks to improve fabrics and details, the Castelli Sanremo 4.1 Cycling Speed Suit is as good as ever at giving you race-winning performance. 

    Cycling Fast Needn't be a Drag

    The Sanremo 4.1 Cycling Speed Suit derives its excellent comfort and performance mix by integrating an aero upper 'jersey' and shorts into a seamless one-piece unit. It's just as convenient to wear as a regular bib short and jersey combo but aerodynamics and comfort are vastly improved. 

    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. 

    Dyed fabrics are also now used for the speed suit, replacing the sublimated fabrics used to print up the pro team kits. It may not sound like much, but it gives a much richer more saturated finish, boosting your race-winning style as you raise your arms across the finish line.

    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 moisture 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.
