TRI-PORTER SPORTSBAG  The Ron Dorff Tri-Porter Sportsbag is the result of the brand’s latest collaboration, this time with French accessory designer Florian Denicourt. The two brands have combined Swedish functionality with French style to create the ideal multi-function sportsbag for men.  The ultra-resistant fabric is made out of ballistic nylon, a fabric developed during WWII to protect airmen from flying debris and fragmentation, and guarantees top resistance against wear and tear. As the name suggests, the Tri-Porter Bag can be worn in three different ways: By hand using the double calf-skin handles. On the back using the rucksack straps in nylon and calfskin.
