My clear bottles are discolouring, what is going on?

Our sports drinks are coloured with natural colourants (beta-carotene and beetroot), which may cause discolouration in some cases. All you need to do is wash your bottle out and leave it open (bottle neck up) to dry in direct sun for a day. The colour will lift.

So what's all this hype about your Isostar bottles?

Well nothing much... except they are the best bottles E.V.E.R! They are nice and soft, allowing you to squeeze them easily, the top valve locks to prevent leaking, and it doesn't pop down every time you drink so you won't get irritated. Best of all, they are BPA free! We source them from Switzerland and give full kudos to the Swiss for having created such an amazing bottle!
