We champion a bunch of labels with sustainable credentials at OPUMO, each of which is candid and transparent about its method and its effects. From the fabrics used to the production methods and working conditions of its employees, we thought this was worth commending, so we’ve rounded up four sustainable menswear brands that are paving the way for others to follow. 

ASKET

ASKET is lighting the way for sustainable menswear brands when it comes to traceability. Even in 2020, the extent of traceability for many brands is a simple ‘made in…’ label. This no longer makes any sense because of the complexity of supply chains.

With eco-friendly labels like ASKET providing in-depth analyses of the origins of each component, we as the consumer can make informed decisions about the clothing that we choose to invest in, and the type of businesses that we choose to endorse.

Artknit Studios 

Based in Biella, Italy, Artknit Studios is famed for its hand-crafted knitwear, the likes of which is among the finest in the world. It’s arguably the brand’s sustainable credentials that are most impressive though. From the factories it uses to its fabrics, it makes every effort to be as kind to the planet, and the people it employs, as possible.

Take for example its eco-cashmere fabric - it’s made in Italy from leftover cuts and excess fabric, reducing its environmental impact by 92% when compared to fast-fashion cashmere.
