Description
Engineered for Your Fastest Race Yet
The Castelli Women's PR 3 Speed Suit is optimized for speed. Built for comfort. Made to break your PR.
When every second counts, the PR 3 W Speed Suit is built to help you leave limits behind. Designed for athletes who aim to beat their personal best, this is Castelli's fastest, most comfortable race suit ever — where innovation meets performance at every seam.
Developed using advanced CFD analysis, 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 help regulate core temperature, while the asymmetric GPS pocket ensures seamless integration of tracking devices without disrupting airflow.
The lower portion of the suit features Premio-based shorts, offering seamless compression, reduced friction, and exceptional aerodynamics. Up top, the ultralight 50-denier fabric — their thinnest and smoothest to date — provides unmatched comfort and speed. The fabric is designed to evaporate moisture right next to the skin during high-intensity efforts, keeping you cool and dry.
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 the swim, bike, and run so you can stay focused on the finish line, not your gear.
