You only need one measurement, your waist.
Between two sizes?
The stretch means neither choice will feel wrong. Size down for a firmer, more supportive fit. Size up if you prefer a little more room, or carry most of your width around the waist.

We spent years designing the most comfortable brief.
Refining the fit, testing fabrics, developing waistbands, and obsessing over the details. The result is our take on the everyday brief designed so you forget you’re even wearing them.
Made from 95% Lenzing™ Modal, a premium plant-based fibre that's buttery soft, moisture-wicking and durable. It’s the kinda stuff you want on your skin down there. Finished with 5% elastane for stretch and shape retention.
