About One

One Denim logo


At ONE, we have a new way of doing things. 

We source the finest denim fabrics, work with leading ethical factories and harness the latest sustainable technologies. We are faithful to time-honoured craftsmanship techniques, but we embrace technological innovations that advance our industry and drastically reduce our environmental impact. 

ONE operates directly online, skipping the traditional brand channels to save you the extra margins. 

The result? Premium jeans, at their true retail value! Check our product pages and see what’s our jeans would have traditionally sold for.

With 20 years’ experience in high-end fashion, it still took us 2 years to develop. So expect nothing less than the highest quality and great fits. Think the finest Japanese fabrics, premium & sustainable production, sartorial detailing and branded gunmetal hardware, sent directly to you in our signature packaging.    

Read up on our fabrics and suppliers in the DNA section of our site.

Our denim factory is BSCI & SEDEX approved, with an A rating. They have sustainable systems in place to drastically reduce water waste and pollution, but we still need to doing more. So we’ve partnered with One Tree Planted and WaterAid by donating a percentage of sales as our way of giving back. Read up about our One for One campaign here.
