The TYR Avictor Prelude Open Back Kneeskin is an elite-level technical racing suit engineered for competitive swimmers looking for maximum speed, compression and efficiency on race day. Developed with input from elite swimmers, the Avictor Prelude combines advanced hydrodynamic technology with a highly compressive, race-ready fit.
Featuring Hydrosphere Technology, the suit is designed to repel water rather than allow the fabric to become saturated. This helps optimise body position, reduce drag and keep the suit lightweight through multiple races. Speed Dry Fabrication further enhances water repellency while helping the suit maintain its compression when wet.
TYR's Supersonic Flex Bonding uses fully bonded seams with 360-degree stretch, delivering strong compression and core stabilisation without unnecessarily restricting natural swimming movement. The open-back design provides additional freedom through the shoulders and upper body, making it a popular option for swimmers who prefer a less restrictive racing fit.
Constructed from 70% Nylon and 30% Lycra Spandex, the Avictor Prelude combines lightweight performance with powerful compression and support

Important: TYR says that if measurements point to different sizes, use the hip measurement as the primary guide. These are race suits, so they should feel considerably tighter than normal swimwear. (TYR New Zealand)
