Premium men’s lifestyle brand Ron Dorff has collaborated with French accessories designer Florian Denincourt of a new multi-functional sports bag that can be worn in three different ways.

The Tri-porter bag is made in France from ultra-resistant ballistic nylon, a fabric designed to protect airmen from flying debris during WWII. It can be worn in three different ways, in the hand via the grab handles, as a rucksack or across the body.

Priced at £325 the bag will be available from 1 September and Ron Dorff’s London Covent Garden store, its Paris store and online.

Ron Dorff was founded by Frenchman Jérôme Touron and Swede Claus Lindorff (the brand name comes from joining the ends of the pair’s surnames) and the range covers, leisurewear, loungewear, swimwear and accessories. It has a growing global wholesale base and earlier this year opened its London store on Earlham Street.

Florian Denincourt is a renowned French accessories brand for men and women and is known for creating sleek leather bags with its signature multiple pocket design. Its Paris flagship store on rue Charlot in the Upper Marais district is close to the Ron Dorff Paris store on the same street.
