Before 1994 or so, the only water bottles I owned were discount store-types. The kind that inserted into a bicycle holder or were given away as promotional items. Then I got to college and everyone was sipping from these hard plastic things called "Nalgenes."
I succumbed to the inevitable and got my first Nalgene soon thereafter, a cheapy one from the Campmor catalog. From there, I went on a Nalgene rampage. Soon enough we probably had a dozen of them, many brightly hued and in all shapes and sizes.
Then whispers about BPA kept floating around and somewhere about 2005 I got a metal Sigg bottle. Whew, what did we do before Nalgene and Sigg? Before the time when sipping a sports bottle at work just seemed weird.
So we accumulated a Sigg collection, too. A couple different shapes and sizes, smug in our progression from the Nalgene tyranny. Then this article came out.
