When the "world's best travel jacket," BauBax, was launched at the end of last year, the company behind BauBax set up a new website, press releases, and a social media campaign. Before launching to a wide audience, the company rolled out the jacket to a smaller pilot group for feedback. The company discovered the jacket was having trouble zipping up and that some of the pockets were in awkward positions for customers.
