## Long description

Hydro Flask HF-Butelka 21oz Standard Mouth with Flex Straw Cap, Surf is a 21-ounce (approx. 621 ml) insulated stainless steel water bottle designed for everyday hydration. The bottle uses double-wall vacuum insulation to reduce heat transfer and help maintain beverage temperature for extended periods. The standard mouth profile fits most cup holders and accessories, while the Flex Straw cap offers convenient sip access without having to tilt the bottle. Its corrosion-resistant stainless construction and powder-coated exterior provide a durable, portable container for commuting, outdoor activities and travel.
Advantages
The bottle’s vacuum-insulated stainless steel body provides reliable temperature retention for both cold and hot drinks. The Flex Straw cap enables easy one-handed sipping and reduces the need to remove the lid for quick hydration. A standard-mouth opening balances ease of cleaning with compatibility with many accessories. The powder-coated finish improves grip and resists scratches, while the overall construction is built for repeated daily use.
Suitable for
 Daily commuting and office use
 Gym and fitness sessions

Key specifications
 Capacity: 21 ounces (approx. 621 ml)
 Material: stainless steel body with powder-coated exterior
 Insulation: double-wall vacuum insulation for temperature retention
 Mouth type: standard mouth

How to use
Fill the bottle with the desired beverage and secure the Flex Straw cap by aligning and pressing until it closes. Use the straw for sipping without tilting the bottle; for hot liquids ensure the cap is correctly seated before use and take care to test beverage temperature first. Clean the bottle and cap regularly: rinse after each use and hand-wash the cap components to maintain hygiene. The standard mouth allows access for a brush to reach the interior for deeper cleaning.
Usage recommendations
For best temperature performance, pre-chill or pre-heat the bottle with cold or hot water for a few minutes before adding your beverage. Avoid using abrasive cleaners or metal scrubbers on the powder-coated exterior to preserve the finish. Do not place the bottle in a microwave; follow manufacturer guidance for dishwasher use of the cap and bottle components.
