However, many people have begun to consider plastic alternatives with the growing concern over the long-term effects of plastic waste. Glass water bottles, in particular, have been gaining popularity due to their environmental benefits and visually pleasing aesthetic, however they tend to be heavier than other options and more prone to breaking.

As plastic is not biodegradable and can take centuries to decompose, plastic bottle usage contributes to significant plastic waste. 

In addition to their environmental impacts, many plastic bottles also contain Bisphenol A (BPA), which has been linked to numerous health problems and subject to increased concerns in recent years. Plastic bottles are also more prone to cracks and deformation due to their lightweight design, making them less durable compared to other options.

Glass bottles are also typically heavier than metal or plastic bottles, and paired with their delicate structure make them a poor choice for active individuals looking for on the go hydration.
