Trying to Stay Trendy

I know that we have lot of trends in our society. But the trend that really baffles me is the water bottle trend. Has anyone else noticed this? Maybe because we've become a pretty health conscious society, but seems like every 2 years we get a new water bottle that is way better than the last style of water bottles for some strange reason.

We used to just use regular old bottled water. But that wasn't very environmentally conscious.



So everyone decided to start using Nalgene bottles. I liked the Nalgene bottles. They seem pretty useful, environmentally friendly.

But then there was some study about plastic harming your water. So then everyone started to use the Sigg water bottles.

I really like my Sigg bottle. Probably just as much as my Nalgene bottle. I'm not quite sure why, but even though Sigg bottles are still everywhere (and I think they keep water colder for longer), now the new bottle is the Camelbak bottle. I don't know what happened to the fear of plastic harming the water though.

I have yet to use this one. It appears I missed the day in the law school where everyone got a free Camelbak water bottle. But you know what, I'm ok with that. Because I don't really need another water bottle.

Can anyone explain to me this water bottle trend? It seems so incredibly strange?
