So what is the safest drink bottle to use?

I have a stainless steel one, but it has some sort of lining.

I'll second the vote for Klean Kanteen - I love mine. Also worth looking at is LifeFactory. They have glass bottles with silicon sleeves, that are quite sturdy. I've dropped mine a number of times and it hasn't broken.

They also make baby bottles and food storage containers, if that's something you need.

LifeFactory is just normal soda-lime glass, AFAIK. They can shatter from drops of a couple feet.

They can, but in my experience, they don't. I'm not sure if it's the silicon sleeve around it, or what, but I've dropped mine a number of times and it's been fine.

What stainless bottle do you have? My Klean Kanteens are unlined stainless. If you get the right lid it'll be stainless lined with a silicone seal too.

Klean Kanteen is stainless steel, but doesn't have a lining. I also have one of these (the glass bottle is made in japan): http://www.amazon.com/Takeya-Classic-Bottle-Silicone-22-Ounc...

Something you enjoy drinking from.

Polyethylene and Polypropylene.

Same advice as when the BPA thing first came out.

They went back to the old plastics with a different plasticizer than BPA, but it's best to just use a plastic that doesn't need a plasticizer in the first place.

If you can keep from breaking it, lead-free glass.

I recently bought a 22oz Lifefactory glass bottle. Mostly covered with silicone for durability. It's a bit heavy, but otherwise great.

Only downside is that the cap is made out of polypropylene, but polypropylene is apparently BPA, BPS, and phthalate free. (May still have other issues, of course.)

Do the klean kanteen or whatever steel ones smell in a day or two like the SIGG ones I used to get? They were the reason I switched to plastic. You had to constantly scrub them and put cleaning pills in them.

The "classic" Sigg bottle is actually lined with plastic, and I find the narrow neck makes them harder to clean as well.

specialized bike bottles use a glass like interior coating that has shown no leaching in some tests.

Bike bottle interior coatings are not very durable. They're OK for a while if you only drink water and do not scrub the inside with anything abrasive at all. But one good scrubbing with a stiff brush and a few days drinking juice out of that thing, and it will taste bad, probably until you throw it out.

Most people want their bike bottles to be squeezable, so some tradeoffs are made. Everyday bottles can be rigid, so stainless steel (or glass) makes more sense.

Just to be clear i'm talking about the "Purist" bottles made by Specialized the company which use a proprietary coating that seems to work well, not bike bottles in general. See for example [this review](http://www.cyclingnews.com/features/product-review-specializ...). I only recently discovered the bottles so can't give a long term review, the manufacture does recommend against scrubbing them.

Uncoated stainless and glass are great options as well but not practical for some uses.

we buy a lot of these as promo/schwag materials for our business (ridewithgps.com, a bike software website/apps) and they certainly do wear out. I end up rotating mine our after 6 months, and i do not wash them with anything but the soap + water + shake method. the lining wears off and you are left with a plasticky tasting bottle. even new, if you let them sit with water in them for a couple days they'll taste slightly of plastic, so it's not perfect.

much better than any others we have tried though, so worth it.

Nothing like the ol' pal "Glass" and/or Stainless Steel...
