The bottle from the company Back Me Up is made of aluminum, lightweight but less resistant to impacts than stainless steel. It is recommended to be used only for water and not for acidic beverages such as fruit juices, which can corrode its interior material over time. Additionally, it is also a thermos, which has the property of maintaining the liquid's temperature stable for a long time, such as during summer at the beach.
