I've used one of the BPA-free bottles from camelbak and can't tell the difference between it and a polycarbonate bottle.
That said, I usually use the translucent white nalgenes, which have no BPA, simply because they are cheaper and I lose water bottles a lot.

Not completely. The HDPE bottles (white semi-flexible ones) don't contain the BPA that is in the polycarbonate ones. the hydration bags are also BPA-free.

Another good thing about the HDPE bottles: if you use the Guyot Firefly, the translucent bottles make an excellent lantern for camping. The PC bottles suck for using the Firefly.

Haha - that's exactly the reason I got a firefly for my HDPE bottle, it looks cool glowing through the foggy white, and just looks crappy on a clear nalgene. A good night light but I wouldn't want to use it to read or navigate a rocky trail.

a family member of mine works at eastman (the company making tritan) and i have a few of the sample bottles. they're the same kick-ass bottle (light weight, impossible-to-break,etc.), minus the toxin. if i recall, the only real drawback is that the plastic gets "cloudy" sooner than the current bottles (though i don't really consider that a major problem, especially since it takes years for that to happen.)

It's funny, I have this theory that there is a karmic circulation of nalgenes in the world. I used to lose them all the time.
Then a couple years ago I bought a subaru from my buddy (who is also a climber and a gear whore) and my car literally eats gear. I have almost 20 nalgenes. 20!

Isn't the cloudiness just from surface scratches?
Also, it was interesting the that the article says those metal bottles aren't necessarily toxin-free either...so much for that trend.

as far as i know it actually happens from the plastic slowly changing chemical composition; but, give me a few minutes and i can probably get the answer straight from the source.

I've always felt a little guilty about buying Nalgenes (I do because of their convenience and usability) because of their lack of recycleability (if that's a word). But they are so easy to use: climbing, camping, work, travelling, etc.
I probably won't stock up now that there are two reasons to not buy them.

This is a valid point.

Does anyone know if the Cambelbak bottles are impacted or if they use BPA?

off topic, I know, but a friend of mine got me a firefly, and I appreciated the gesture, but asked myself: Why can't I just put my headlamp around this like I have been doing and save the weight?

What about the Outdoor products - Cyclone Hydration bottle? Is that free of poison? W/e I'll probably still drink from it even if it is. It can't be worse for you than eating fast food.

Future fear...
We'll all start hearing a lot about eco friendly and biodegradable plastics and containers if not now soon and....
they actually "degrade" after a while releasing stuff into the product inside due to the very nature of the ingredients in the bottles "bio-degradable materials or recycled materials" they will not last forever or maintain their composure so to speak.
I miss the old glass 16 oz Pepsi bottles with the pop off tops myself!

The aluminium bottles have a coating on the inside that prevents the aluminium from oxidizing and getting into the water. From what I've been told, were you to dent the bottle and crack that coating, that aluminium can get into your water as aluminium oxide. Fun times.

Nope. The initial study from 1965 has since been discredited. While it remains a popular belief, there is no proof of a causal relationship between Aluminum and Alzheimers. Current studies are actually indicating more and more that this seems to be completely false. Feel free to continue drinking beer from cans and knowing that the only reason we can't remember anything is because of alcholism.

colatownkid wrote: nalgene currently (until a few days ago) sells two varieties, "soft" and "hard," both of which contain the toxin BPA. The soft variety is a polycarbonate with the recyclable designation number 5; it's pretty strong stuff, recyclable, but has a lower melting point and probably isn't advised for boiling water. The hard variety is a type of lexan with the number 7 designation; it is not recyclabe but is ridiculously durable and can hold hot liquids with no risk of deformation. i got this information on pretty good authority as it's straight from the guy who invented the tritan plastic.
If your source is as represented, I'd say that the guy who invented Tritan needs to go back to college chemistry before he constitutes a "pretty good authority." #5 plastic is polypropylene which is not derived in any way from BPA-containing sources.
Further, if you flip over a "soft" Nalgene brand bottle, I think you'll find a #2 on the bottom. #2 indicates that the plastic is high density polyethylene ("HDPE"). I believe that Nalgene also manufactures low density polyethylene bottles, as well-- which happen to be stamped with a #4. Neither HDPE nro LDPE are derived in any way from BPA-containing sources. I find the LDPE bottles to be a bit on the soft side for my needs, but I've been using the HDPE bottles for years without any problem.
