CASTELLI BTW Short Sleeve Trisuit
Dominate your next race with the CASTELLI BTW Short Sleeve Trisuit, a masterpiece of aerodynamic engineering designed for the competitive cyclist and triathlete. Born from a relentless pursuit of speed, this men´s skinsuit is the definitive choice for moments when every watt and every second counts. Through extensive Computational Fluid Dynamics (CFD) analysis and significant real-world testing, Castelli has created the fastest road racing suit, optimized for high speeds when the race splits apart. The “BTW” in its name stands for “Break The Wind,” a promise this suit delivers with unparalleled efficiency.
Engineered to be the fastest option for high-speed road racing and demanding triathlon bike legs, the BTW Trisuit employs a sophisticated, multi-fabric approach to manipulate airflow. Strategically placed dimpled fabric on the shoulders and short sleeves actively trips the boundary layer of air, reducing drag and allowing you to slice through the wind with less resistance. This is complemented by a perfectly smooth body fabric that minimizes skin friction and encourages laminar flow, ensuring you remain as slippery as possible at peak velocity.
Comfort is not sacrificed for speed. The short portion of the suit is constructed from Castelli´s proven Premio-based fabric, providing exceptional compressive support and aero comfort without restrictive seams. At its heart lies the legendary Progetto X² Air seamless seat pad, a top-tier chamois renowned for its ability to provide breathable, all-day comfort during the longest and most intense efforts. This crucial feature makes the BTW suit a formidable weapon for Ironman distances and all-day grand fondos.
Functionality is paramount in a race-day garment. A full-length, 2-way YKK® zipper allows for effortless on/off and superior ventilation control, giving you the power to regulate your core temperature on the fly. In a brilliant piece of race-ready design, the sleeves are specifically constructed to hold race numbers securely over the two integrated rear pockets, eliminating the need for pins that compromise aerodynamics. Finishing touches like the subtle, lasered tone-on-tone logos and a stitched scorpion patch showcase the premium quality and Italian craftsmanship synonymous with the Castelli name.
