Pretty sure Airblaster invented these. Actually true. Maybe. The first outerwear pants that Airblaster ever developed in around 2004 had elastic bottoms. They brought samples to the trade show. People said, "Ha-ha. ... Seriously, though. ... They're going to have normal bottoms, right?" And they were like, "Duh. Yes. Like, that elastic is just a joke, obviously." and they changed them. But it wasn't a joke. We were crying. But now they can have the last laugh. Teehee.
