The other day, as I was shopping for underwear, I noticed that one brand had an unusual package. It was a heavy duty bag with a zipper on the top.
A few years ago, I bought a sports blanket that came in a heavy duty plastic bag with a zipper on the top. I guess the idea was that you could keep the blanket in the protective bag until you needed it. That way, it would be protected from the elements.
So, maybe the same applies to the underwear. The briefs are kept in their protective bag, away from the elements. That way, when you need a pair, they are clean and dry.
But, since this was not a sporting goods store, I suspect that this was just someones idea of packaging. And, since the briefs were on sale at the same price as the ones in the cheap plastic bags, I suspected that they were not a big seller.
The underwear is nice but I will through the heavy duty plastic bags away.
