About Us

Most active-lifestyle clothing only works for one part of your day. The gym kit doesn't translate to the walk home. The cotton tee doesn't hold up to the workout. The hoodie looks tired after a year.

Witness is built for all of it. A UK active-lifestyle brand for men and women, structured around four collections that cover the gym, the daily routine, the standout pieces and the layer on top. Cut to fit real bodies, sized XXS to 3XL across most of the range, and made to hold up past one season.

Made to Fit

Witness patterns are graded across a broad size range, with most pieces available from XXS to 3XL. Each product page explains how the garment is intended to sit, whether that's loose, oversized, regular or close to the body. Where a design doesn't work properly across the full size range, we don't pretend that it does. The available sizing is shown clearly on each product page.

Built to Last

Some pieces are built around weight. The heaviest cotton tees in the range sit between 280gsm and 340gsm, and a single jacket reaches 445gsm where structure matters most. Some pieces are built around stretch and recovery: nylon-spandex and poly-spandex blends that hold shape through movement and washing. Some use Sorona®, a partly bio-based fibre added to cotton blends for softness, drape and quicker drying.

What Witness Means

A witness sees clearly and tells the truth about what is there.

That's the posture of the brand. We make clothing for the way people actually live, in the sizes they actually wear, from the fabrics actually used to build them.

For active lives. For all shapes and sizes.
