What Our Gearhead(R) Experts Are Saying:"I wore the PR 3 Speed Suit during my last tri and instantly noticed the aerodynamic difference-especially in crosswinds. The ribbed sleeves are slick, and the fabric feels ultra-light without sacrificing support. The GPS pocket is a smart touch, and nothing beats the feel of Premio-based shorts during long efforts."When every second counts, we need a suit that refuses to compromise. Castelli's PR 3 Speed Suit is their most aerodynamic and comfortable race suit yet, and it shows in every stitch and seam. Engineered using CFD analysis and proven in the wind tunnel, it's built to cheat drag while keeping us cool and locked in during max-effort efforts. The suit pairs Castelli's ultralight 50-denier fabric with strategically placed ribbed sleeves to cut wind resistance and shed moisture fast. Premio-based shorts bring long-distance comfort and race-level compression, while functional details like an internal neck pocket for cooling packs and an asymmetric GPS pocket keep our focus forward. With a near-skin fit and engineered airflow, the PR 3 Speed Suit is our go-to for PRs, podiums, and everything in between.
