This size guide covers our running tops and clothing, which run from XS through to 3XL.
How to measure
- Chest. Measure around the fullest part of your chest, keeping the tape level and not pulled tight.
- Body length. Measure from the highest point of the shoulder straight down to where you want the garment to finish.
- Compare with a top you own. The quickest check is to lay flat a running top that already fits you well and measure that instead.
Choosing between two sizes
Our tech tops are cut for running rather than for lounging, so they sit closer to the body than a standard cotton t-shirt. If you are between sizes, or you prefer a looser fit over a base layer in winter, size up. If you want the fabric to do its job at speed, stay with your usual size.

Fabric and fit notes
Tech tops are lightweight, breathable and quick drying. They are designed to move with you and to shed sweat rather than hold it, which is why the cut is closer than casual wear. Printed designs are applied so they do not sit as a heavy, non-breathable panel across the chest.
