Choosing the correct Orca trisuit size is essential for comfort, flexibility and race-day performance. A well-fitting trisuit helps reduce drag, improves mobility and keeps you comfortable throughout swimming, cycling and running stages. Use our Orca trisuit size guide below to compare measurements and find the best fit for your next triathlon, training session or endurance event.
An Orca trisuit is designed to deliver comfort, aerodynamics and flexibility across every stage of a triathlon. Whether you are competing in sprint events, long-distance races or regular training sessions, choosing the correct trisuit size helps improve comfort, reduce distractions and maximise performance throughout the race.
A properly fitting trisuit should feel streamlined and supportive without restricting movement. Orca trisuits are designed with lightweight technical fabrics, compression panels and quick-drying materials to help you move efficiently through the swim, bike and run disciplines.
Use the Orca trisuit size charts below to compare your measurements and find the best fit for your body shape and race style.
An Orca trisuit should fit close to the body to reduce drag and improve aerodynamic performance while still allowing full freedom of movement. The fit should feel supportive across the torso, shoulders and legs without excessive tightness or bunching.
Key features of a good trisuit fit include:
Because trisuits are designed for multi-discipline performance, they typically fit tighter than casual sportswear. Compression-style panels are common and help support muscles during longer events.

Orca trisuits are available in a range of styles designed for different race distances, performance levels and personal preferences.
When choosing the right trisuit, you may want to consider:
Some athletes prefer maximum compression and aerodynamic performance, while others prioritise flexibility and comfort for training and longer endurance events.
For the most accurate sizing results, measure yourself while wearing lightweight clothing and standing naturally. Use a flexible tape measure and compare your measurements carefully against the Orca trisuit size charts.
The most important measurements usually include:
If your measurements fall between sizes, the best option may depend on whether you prefer a tighter race fit or slightly more comfort during longer events.
