Clean Athletes | Clean Clothes 

It took us a clean 42.54 seconds to win a Silver Medal at the Olympic Games in Beijing 2008.

That Silver medal turned into Gold, when the winning team was disqualified due to a failed drug test.

While it is abundantly clear that dirty athletes have no place in sports, we are less outspoken when it comes to the clothes we wear while performing.

That is what we would like to change. Clean athletes should also wear clean clothes!




Because from the very beginning 42I54 has always put sustainability at the top of their agenda.

The environmental and sometimes social challenges are divers and complex, but the founders make a conscious effort to be an honest and transparent brand, by largely working with local manufacturers and suppliers.




Today the designers are proud to add a new layer to their brand, by using recycled materials. We are convinced that great design should also be sustainable!


  • 42I54 launched its first 100% sustainable FW19 capsule collection. The brand teamed up with renowned textile companies who propose fabrics made from a fiber called SEAQUAL and NEWLIFE. Recycled from ocean plastics, it is a positive product of men’s negative intervention with the sea.
  • No to overconsumption. 42I54 has since FW19 taken the firm decision to quit the track of fast fashion by producing two reasonable collections, instead of four. We now offer a variation of bestsellers and exciting newness.
  • We are now packaging all purchases in a reusable RePack packaging. Discover how it works here.




The next SS20 collection will be 100% sustainable.


  • Recycled fabrics developed with fibres created with ocean waste and plastic bottles.
  • Organic yarns working with GOTS (Global Organic Textile Standards) certified factories.
  • Hangtags produced with recycled paper.




There is still a lot of work to be done.


  • Give a second life to stock and leftover fabrics from previous productions.
  • Biodegradable packaging.




Being a 100% sustainable company in the way we work, produce and live.
