At Gunn & Grant we are committed to sustainability in every aspect of our work. We believe that garments should be built to last. We are not in the fashion business and as such we want our timeless designs to encourage a lifetime of wear. We want our tartan trews to be passed down, repaired when needed, altered, and reused.


Tartan trews by Gunn & Grant are made from pure new wool. Wool is an incredible material. It not only looks and feels luxurious when made into a pair of trews, but it's also a highly sustainable fibre. It biodegrades quickly and demands fewer washes due to its natural anti-bacterial and anti-odour properties. Wool is also a renewable resource, with Scotland's own sheep providing much of the raw material used to create the yarns needed for our hundreds of tartans.

To contribute towards our sustainability ambitions, we offer complimentary alterations for every pair of trews we make. And we provide this service at any point during the lifetime of the trews. By doing this, we can make sure our trews are used for longer, cutting down on unnecessary waste.

Locally Sourced

Most of our wool is sourced from Scottish sheep. By doing this we can reduce transportation distances and so reduce emissions. We believe we make a sustainable luxury Scottish product, and that this is only possible by drawing heavily on the amazing local landscape and the resources it provides.
