## Long description

Hydro Flask HF-Butelka 21oz Standard Flex Cap Trillium — 21 oz insulated stainless steel is a double-walled, vacuum-insulated water bottle designed to keep beverages hot or cold for extended periods. The bottle combines stainless steel durability with a Standard Flex Cap that seals securely while remaining easy to open and close. With a 21 oz capacity, it is sized for daily use, travel, gym sessions and outdoor activities while maintaining a leak-resistant profile and BPA-free construction.
Advantages
The insulated stainless steel construction ensures reliable temperature retention for both hot and cold drinks, while the double-wall vacuum design minimizes condensation on the exterior. The Standard Flex Cap provides a comfortable grip and a secure seal that reduces the risk of spills during transport. The bottle’s finish resists wear and is easy to clean, and its 21 oz capacity balances portability with enough volume for hydration throughout the day.

Key specifications
 Capacity: 21 oz (approximately 621 ml)
 Material: Insulated stainless steel (double-wall, vacuum insulated)
 Cap type: Standard Flex Cap (flexible, sealable closure)
 Finish: Durable exterior coating resistant to wear
 Safety: BPA-free construction
 Design: Leak-resistant profile with condensation-free exterior
How to use
Fill the bottle with a beverage and secure the Standard Flex Cap by aligning and snapping it closed to ensure a tight seal. For hot liquids, allow a short cool-down period before closing the cap to avoid pressure build-up. To maintain insulation performance, pre-warming or pre-cooling the bottle briefly with hot or cold water can help. Hand wash recommended for the cap and bottle exterior; the interior may be rinsed or cleaned with a bottle brush and mild detergent.
Usage recommendations
Do not place the bottle in a microwave or freezer. Avoid using bleach or chlorine-based cleaners. Inspect the Standard Flex Cap regularly for wear and replace if the seal becomes compromised. For optimal temperature retention, fill the bottle close to full and limit frequent opening.
