Last month, we reviewed the new BPA-free CamelBak Better Bottle. And with the recent news about the potential dangers of bisphenol A, even die-hard Nalgene fans are turning away from their old polycarbonate bottles.

Now you can, too. We have one BPA-free CamelBak bottle to giveaway to a lucky reader.

To be entered in the contest, just leave a comment in one of our posts this week (this one excluded).

Two quick rules:

1. You must be a resident of the U.S. or Canada,
2. You will be allotted one entry per comment per post. So if you comment more than one time on a post, that’s fine, but you’ll only be counted once for that post.

We’ll randomly select the winner on Sunday, May 11th.

We’re excited about spreading the love of BPA-free water bottles, and we hope this will generate some insightful discussion among our readers. At least one post this week promises to be controversial - we’ll give you the 411 on carbon offsets.
