Plastic bottles use a chemical Bisphenol A (BPA) to make them hard and clear. BPA is an endocrine disruptor, proven to be hazardous to human health. Bottling plants themselves use millions of gallons of water to make the plastic bottles which lead to water shortages affecting nearby residents, especially farmers. This sturdy stainless steel water bottle is safe for nature as well as for you as there is no leaching of chemicals. It is easy to clean and retains no flavour while the insulation keeps water cool/hot for several hours. It is a cheaper alternative to buying plastic bottles repeatedly and is also more environmentally responsible.
