The Shanti stands out because of its membrane lid. This can be opened or closed quickly with one movement. In the ‘open’ position the bottle is always ready for use. The membrane system prevents it from leaking. Only when you squeeze the bottle the water will come out, exactly in the amount you want. The Shanti can also be ‘locked’.
The Bio-Bottle has the same characteristics as the other Tacx bottles, but it distinguishes itself due to the plastic of the bottle being biodegradable. Adding a small amount of the Bio-batch material alters the molecular structure, which makes the material decompose into biogas and biomass. These nourish the soil and are entirely absorbed by nature.
