Functionally, glass water bottles are superior to many other materials. Unlike plastic, glass does not retain flavors or odors, ensuring that each sip is as refreshing as the first. This quality makes glass bottles particularly suitable for those who enjoy infusing their water with fruits, vegetables, or herbs. Furthermore, many glass bottles come with a protective silicone sleeve. This not only offers a better grip but also guards against potential breakage, making them more durable for everyday use.
