Castelli PR 3 Women's Speed Suit

When every second counts, the PR 3 W Speed Suit helps you push the limits. Designed for athletes looking to break their personal bests: This is our fastest, most comfortable race suit yet, where innovation meets performance at every seam. Using advanced CFD analysis, every fabric panel and seam placement has been optimised for maximum aerodynamic efficiency. Specially engineered ribbed sleeves reduce drag at race speed and deliver measurable CDA gains that give you an edge when it matters most.

Racing in extreme heat? The internal neck bag for ice is strategically positioned to help regulate core body temperature, while the asymmetrical GPS bag ensures seamless integration of the tracking device without disrupting airflow. The lower half of the suit features Premio-based shorts for seamless compression, reduced friction, and exceptional aerodynamics. On the upper body, the ultra-lightweight 50-denier fabric—our thinnest and smoothest yet—delivers unmatched comfort and speed. The fabric is designed to wick moisture away from the skin during high-intensity activity, keeping you fresh and dry.

A covered, drag-free rear pocket provides secure storage for your nutrition without adding bulk. The KISS Tri seat pad delivers all-day comfort and performance during swimming, cycling, and running, so you can focus entirely on the finish line and not worry about your gear.
