Oh No! My T-Shirts Have Gone Stale!

One of the consequences of my new job was that I needed to buy some new clothes. I’m not one of those folks who goes out and buys a new wardrobe at a whim, but my first day on the job convinced me that the jeans and polos that been “business casual” at the old job weren’t going to cut it. (For the first day of the job, I’d worn a tie and jacket, and thus put off clothes shopping that much longer.)
While I was buying dress shirts and slacks, I also picked up some new T-shirts to go with them. Standing at the checkout line, I noticed something most unexpected about the T-shirts’ packaging. Along with the usual size and quantity, Hanes had also prominently labeled the shirts as “tagless.” I’d discovered a few years earlier that they’d stopped putting tags in the T-shirts (because they itch!) and that was enough to make me choose them over another brand. But what really got my attention was that the bag was also labeled as resealable.

Six weeks later, I’m still trying to understand the marketing angle on this. What are you going to store in it besides T-shirts? I could see using the bags to keep things dry on a camping trip, but that’s not a common use, is it?
All I can think of is the old commercials for Zip-Lock and Glad bags about how you could reseal the bag to keep the contents fresh. Is that a problem for T-shirts?
