Same summary

The Leitz Cosy thermo bottle, blue, is a compact design with a capacity of up to 500 ml, which best suits your daily hydration needs on the go, at school or in the office. Due to its insulated type, it maintains the temperature of hot or cold drinks, but the smaller capacity means a limitation for longer trips or intense sports, where additional capacity would be needed. It is recommended for those users who are looking for a balance between convenience and effective temperature retention without the additional complexity of smart features.
