  • Castelli Body Paint 4.X Speed Suit Long Sleeve

    The Body Paint 4.X Speed Suit Long Sleeve from Castelli is unashamedly all about cycling as fast as you can. Whether on the track or time trialling it's engineered to ensure optimal aerodynamics as speed increases.

    While you may have the aero bike, aero-bars, aero wheels and aero helmet, what about you and your body aerodynamics? The Body Paint 4.X Speed Suit Long Sleeve delivers a significant boost to your efficiency through the air as you get up to speeds of 45km/h and upwards. Two years of design, computer modelling and real-world testing, both at the Norwegian Technical University and on the WorldTour make this the most refined suit you can possibly own. 

    The fit has been optimised for time trial riding positions, with the seam count reduced so as to offer streamlined airflow and also outstanding comfort. Longer cut legs, with flat grip tape grippers, provide a smooth transition between your suit and legs while arm thumbholes keep the suit perfectly positioned. You'll also immediately notice how close to the body the suit fits - remember it's designed for lean pro-tour riders so expect a second-skin fit. 

    Last,  but by no means least, a clear window pocket to the back makes space to display your race number, keeping it smooth, visible and drag-free. There's also the bonus of not having to use safety pins on your favourite race suit.

    Progetto X2 Air Seamless Seat Pad

    Inside the Body Paint 4.X speed suit is Castelli's renowned Progetto X2 Air Seamless seat pad. 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.
