Bisphenol A - Bottles Holding Hot Liquids Leach More Bisphenol A - thedailygreen.com

This says, pretty much, don't put hot drinks in your Nalgene bottles. I guess it all comes back to that, "Don't heat your plastic" issue we've discussed.

Sigg bottles are awesome. We have a small one for ds (with cars on it) and a bigger one that we share (need to get a second). They are a tad pricy, but totally worth it if you drink a lot of water (as you should)! And you get free shipping if you order from the link above, so that's cool!

It would be a small investment for me to switch all our nalgene bottles out. I'm glad I don't put hot liquids in them.
