Ever wonder why there's a teeny-tiny pocket above the regular ones in the front of your jeans? Or, more likely, have you ever gotten your thumb stuck in there due to its teeny-tiny smallness? Well, wonder no longer.

有没有想过，牛仔裤口袋上方的迷你口袋用途何在？或者，更有可能的情况是，你有没有把大拇指插到这个口袋里然后拔不出来的经历？哈哈，我们今天就来揭开这个谜底。

It's a watch pocket, originally for men who wore pocket watches and needed a protective place to store them. Though, as Levi's points out, the pocket has also served many other purposes over time, from condom storage to coin hoarding¹.

这其实是一个表袋，最初是为有怀表的人设计的，怀表放在这里面刚刚好。不过，李维斯牛仔生产商也指出，这个口袋的功能多得很，放得了套套，也囤得下硬币。

Faaahbulous!

棒呆了啊！

The burning question arose last week after curious minds re-discovered a Quora thread in which users have discussed this mysterious fifth pocket for years.

上周，一些好奇人士挖出了问答网上询问牛仔裤第五个口袋用途的帖子，于是这个被讨论了多年的话题再次沸腾起来。

The Levi Strauss blog confirms their conclusion: "The first blue jeans had four pockets—only one in back and, in the front, two plus the small, watch pocket. This extra pouch² has served many functions... condom pocket, coin pocket, match pocket and ticket pocket, to name a few."

李维斯创始人李维·史特劳斯在博客中给出了最终答案：“最开始的蓝色牛仔裤有四个口袋，背面一个，前面两个，外加一个迷你表袋。这个小口袋功能强大，能装的东西可不少，比如避孕套、硬币、火柴、票据等等。”

The pocket appears on the oldest pair of jeans in the Levi's archives, which date to about 1879, Levi's historian³ Tracey Panek told HuffPost.

研究李维斯的历史学家特雷西·帕内克告诉《赫芬顿邮报》，档案显示，李维斯生产的第一条牛仔裤上就已经出现了迷你表袋，能追溯到大约1879年。
