Optimized for speed. Built for comfort. Made to break your PR.
When every second counts, the PR 3 Speed Suit is built to help you leave limits behind. Designed for athletes who aim to beat their personal best, this is our fastest, most comfortable race suit ever — where innovation meets performance at every seam. Developed using advanced CFD, every fabric panel and seam placement has been optimized for maximum aerodynamic efficiency. Engineered ribbed sleeves actively reduce drag at race speeds, delivering measurable gains in CdA to give you the edge when it matters most.
Racing in extreme heat? The internal neck ice pocket is strategically positioned to put ice and help regulate core temperature, while the GPS pocket ensures seamless integration of tracking devices without disrupting airflow. Up top, the ultra-light 50-denier fabric - our thinnest and smoothest to date - provides unmatched comfort and speed. Stay cool and dry through every stage, designed to evaporate moisture right next to the skin during high-intensity efforts.
A covered rear pocket offers secure, drag-free storage for nutrition, keeping your fueling streamlined. The KISS Tri pad delivers all-day comfort and performance across swim, bike, and run so you can stay focused on the finish line, not your gear.
