ECOtankas look modern and very attractive, while at the same time offering one of the most hygienic surfaces that is available.  Stainless steel is very easy to clean and it's unique surface has no pores or cracks to harbour dirt, grime or bacteria.  So your bottle stays completely clean and safe for years upon years. 

ECOtankas are ultra light and durable, they are not lined with any material and they do not break down or leach in any way.  They are completely safe and non-toxic.  A 1 year warranty is also offered against faulty manufacturing.

Fluids can be changed from a juice or sports drink back to water, and there is no tainting or after taste.  Drinks from an ECOtanka always taste beautifully clean and fresh, and the stainless holds them cooler for longer periods of time.
