## Long description

Hydro Flask 21 oz insulated water bottle with Standard Flex Cap in Reef is a double-wall vacuum insulated stainless steel bottle designed to maintain beverage temperature for extended periods. The 21 oz (approximately 621 ml) capacity provides a balance between portability and hydration volume, while the powder coat finish improves grip and scratch resistance. The Standard Flex Cap features a flexible loop and a flip-top spout that helps reduce spills during transport.
Advantages
The double-wall vacuum insulation minimizes heat transfer to keep cold drinks cold and hot drinks warm for hours without condensation forming on the exterior. Durable stainless steel construction resists dents and corrosion for long-term use. The powder coat surface offers a secure, non-slip grip and enhanced durability. The Standard Flex Cap is leak-resistant when closed and provides a convenient carry loop for hands-free transport.
Suitable for
 Daily hydration at work, school, or home

How to use
Fill the bottle with your preferred beverage and secure the Standard Flex Cap by pressing it into place until it seals. For hot liquids, allow a short warming period after filling to avoid scalding when opening. Use the flip-top spout to drink directly or pour into a cup. After use, hand wash the cap and rinse the bottle with warm, soapy water; most stainless steel insulated bottles should not be placed in a dishwasher to preserve insulation performance and powder coat finish.
Usage recommendations
To maintain insulation performance and exterior finish, avoid freezing liquids inside the bottle and do not use abrasive cleaners or metal scrubbers on the powder coat. Periodically disassemble the cap to clean the seal and spout to prevent buildup. Use the bottle for both cold and warm beverages according to temperature guidelines provided by the manufacturer.
