About Eric Wendler Get to Know the Creator of RetroStrap Using his more than 30 years of experience in marketing and business development, Eric Wendler created RetroStrap. How Eric Created RetroStrap For more than 30 years, Eric has used many different briefcases, computer bags and sports bags. He got frustrated by struggling with their standard shoulder straps that dangled, looked sloppy & unprofessional and got in his way. Also, the straps would lay on dirty floors and created a tripping hazard.Eric noticed that other people had the same problems with their straps – see the photos on this page!Eric searched for a useful product to solve his problems but could not find a solution. So Eric decided to create his own product. After a few years of building and testing prototypes, he designed RetroStrap – a retractable strap that he could attach to his computer bag.
