It's one thing to have pure water at home, but what do you do when you want to take some with you in the car, bus or train. For some time we have been looking for a good, non-plastic dinking bottle. With all of the concern about Bisphenol-A (BPA), polycarbonate bottles are not ideal for keeping water in.

Well, we think we have found it! Check out the ThinkSport stainless steel bottles.

The bottles are made from light weight stainless steel so they are virtually indestructible - unlike plastic.

They are double walled and vacuum sealed so they will keep drinks either hot or cold for hours. Not only that, but the outside of the bottle does not reflect the temperature of the contents. so you won't pick up a boiling hot bottle or a freezing cold one.

The ThinkSport bottle has an internal mesh filter designed to prevent tea leaves (or ice cubes) coming through.

You can use them for more than just drinking water!

For example, you might use the 350ml size for cold milk and use the 750ml for boiling water (purified, of course!). Then you can make a cup of tea or coffee wherever you are. Your water stays hot and your milk stays cold.
