What portable drinking container do you use?

I've been reusing the same plastic water bottle day to day for quite some time but recently I have been hearing about the side-effects of BPA leeching from the plastics that make our disposable water bottles and also the ones that are not disposable like Nalgene.

When I'm at home and at work I drink out of a glass mug. But I need something portable. I saw some stainless steel water bottles at Costco for about $15 bucks that I'm considering. What do you use for portability?

Jam it back in, in the dark.

Also, question about the chemicals leeching from the plastic into the reused water. Why is it alright to drink the water that's been sitting in the bottle for a few months, but not the water I put in there twenty minutes earlier?

This is a good point, maybe some chemistry people can help clear this up if there is a valid reason.

Also, in the months I've been reusing soft plastic bottles, I have never left water in it for more than a few hours and after about a month I start to detect a bad taste.

In the long run, some stainless-steel bottle or a nalgene bottle is cheaper anyway.

There's nowhere I can't reach.
