NALGENE SIPPY CUPS!

Now this is a great idea! And who says they have to be just for kids? The best part about these lids is that they fit on regular Nalgene bottles too. Now thats what I'm talking about! This is great for taking a drink when your working out or even driving in the car....no worries abou the spillage! Only one drawback.....you have to suck really hard to get a drink quickly! How do those kids do it?
