We've been out of stock of these for sometime now, but finally they're back in (and selling FAST!). 'The Original Polycarb Pop Top' drinking bottle is a safe alternative to most other plastic bottles that can allow leaching of chemicals into your drinks. As well as being much better for you, its also tonnes better for the environment (watch the trailer to the new documentary 'Tapped' at http://www.youtube.com/watch?v=72MCumz5lq4, if you're not already convinced!) as it can be reused hundreds of times! Ditch your plastic drinking bottles, and pick up one of these today....they're available in 600ml and 1 litre sizes.
