A fanny pack goes in and out of style every couple of years. Looking at world history, ‘fanny packs’ in some form, have been worn for hundreds of years. In the early 90s, when I worked in the retail store I wore a fanny pack. I carried supplies that I used to fix displays. This included basic tools and labels. I did not wear one outside of work. Now I wear a pack. When I exercise! I used to keep my cell phone and keys in my pockets. Those items would fall out. In addition, twice I dropped my driver’s license. A fanny pack secures all my stuff. I recently had to replace one. I got a more fitness-oriented version. I like it a lot.
