Picking a size

Compare the garment measurements to a similar top that fits you well — this is usually more reliable than measuring your body.

Between two sizes? Size up for a relaxed fit, size down for a closer fit.
All measurements have a tolerance of ±0.5 cm (±1 cm for jackets).
For team orders, we recommend sizing up by one if in doubt.

How to Measure

Watch our quick guide to measuring yourself for the perfect fit.
