Quality Innovations

Our aim is to make everyday life more comfortable and efficient. That is why we’ve created technologies to help facilitate simple tasks like going to the toilet quicker to performing better at your sport whilst eliminating discomfort from sweating or chafing.

We believe that detail matters and so, we bring you innovations such as our X-Fly clever access and Coccoon internal pocket device.

Our Technology

The planet first

Better materials and engineering mean that our products last longer. It’s as simple as that. Take our IKON boxers as an example, they will survive and still thrive 100+ washes (more than double our closest average competitor).

Knowing that our products will stand the test of time, we want our customers to invest well and Buy Nice and Not Twice. In doing so, you'll save you money in the long run and reduce waste for our planet. All our packaging is plastic-free and 100% recyclable.
