Probably the most environmentally friendly and lightest water bottle we have ever held. Smartshake produces this bottle, made from 98% sugar cane, directly in Sweden, completely carbon neutral. The screw cap is made of natural cork, which comes from Portugal. Thus, the EcoBottle is probably the best bottle to protect the climate. Naturally BPA and DEHP free and tested for food. The leak-proof bottle has a capacity of 650 ml.
