The Ultra Tri P1x is Zoot’s fastest racesuit, the one its pros have won and set course records in. Shaped by elite athletes, tested in the wind tunnel and proven in competition, it delivers aerodynamic speed without sacrificing support or comfort deep into the race. Every seam, panel and fabric has been refined for measurable gains: a precise race fit, 3D AeroWeave construction and a seamless finish that reduces drag where it matters most, printed in the 2027 Slowtwitch GOODLIFE Racing design.
Features
- Ultra-light 3D AeroWeave fabric on the sleeves and upper back: wind tunnel tested, second-skin material whose raised-ridge construction disrupts airflow to reduce drag
- Precision-cut arm cuffs for a seamless, aerodynamic edge and a race-tuned fit
- Seamless leg construction with internal silicone grippers, no bulky bands
- High-Speed Light ventilation zones across the sides and back for real-world airflow
- Pro Carbon P1x Chamois: upgraded, perforated and fast drying, with targeted support for long course
- Minimalist zig-zag chamois stitching for an ultra-smooth, next-to-nothing feel
- Ships in a reusable, water-resistant storage bag
