With the popularity of New Era caps growing in the sports world (outfitting the NFL, MLB and occasionally other leagues), fans now have more access to these caps for their own collection. Especially with baseball caps, New Era has branded itself as not only for the professional leagues, but also as a fashion statement.
But the trend I have noticed with these caps is that when people buy them, they don’t remove the sticker on the bill.
I am not sure if these people want me to know their cap size or if they actually just stole it from the store. But what it reminds me of is the sticker on newly purchased pants. I think it’s the same equivalency.
