The French national team are known throughout the sporting world as "les bleus" because of their iconic kits, which echo the blue of the French national flag.

French sportswear brand Le Coq Sportif, in collaboration with the French Rugby Federation, have been creating and developing a new kit for the national squad ahead of France hosting the Rugby World Cup in September and October 2023.

Rosa Johnston-Flint talks to some of the creatives behind the design and manufacture of this new kit, and goes to Le Coq Sportif's factory in Romilly-sur-Seine, a small town not far from Paris, to watch the first shirt being made with fabric especially created in France.

Rugby is a rough contact sport, so how do you make a jersey that can withstand tackles while being as light as something worn by a cyclist and looking elegant under the spotlight of a home world cup?
