Choosing the correct Zone3 trisuit size is essential for comfort, flexibility and race-day performance. A properly fitting trisuit helps reduce drag, improves mobility and keeps you comfortable across swimming, cycling and running disciplines. Use our Zone3 trisuit size guide below to compare measurements and find the best fit for your next triathlon, endurance event or training session.
A Zone3 trisuit is designed to provide comfort, aerodynamics and flexibility throughout every stage of a triathlon. Whether you are competing in sprint races, middle-distance events or long-course endurance triathlons, choosing the correct trisuit size helps improve comfort and efficiency from start to finish.
Zone3 trisuits are developed with lightweight technical fabrics, compression panels and quick-drying materials designed to support performance during swimming, cycling and running. A well-fitting trisuit helps minimise drag in the water while remaining comfortable during longer bike rides and runs.
Use the Zone3 trisuit size charts below to compare your measurements and find the best fit for your body shape and race style.
A Zone3 trisuit should fit closely to the body without restricting movement or breathing. The fit should feel streamlined and supportive, particularly around the chest, waist and legs.

Because trisuits are performance-focused garments, they generally fit tighter than casual sportswear.
