Capacity: The capacity is typically around 500 ml to 1 liter, which is a standard size for personal hydration.

Special Features: Some versions of this generic model may be marketed as "smart" water bottles. These can include a digital LED display on the lid that shows the current temperature of the liquid inside, a feature often powered by a small battery.

Design: The design is usually simple, sleek, and cylindrical, with a secure, leak-proof cap. They are often available in a variety of solid colors.
