• Travel and short trips where space is limited

This flask may not be suitable for individuals requiring a larger capacity for long-duration expeditions or group outings, as its 0.5-liter volume is designed for personal use. Additionally, it is not intended for storing carbonated beverages, as the pressure buildup could potentially compromise the seal or cause leakage.

Key specifications

• Capacity: 0.5 liters
• Material: Stainless steel
• Insulation type: Double-layer vacuum insulation
• Color: Black
• Design: Lightweight and compact

To use the Rosberg vacuum flask, start by pre-heating or pre-cooling the interior by filling it with hot or cold water for a few minutes before adding your intended beverage. Once prepared, fill the flask with your drink, leaving a small amount of space at the top to ensure the lid can be sealed tightly. Always ensure the cap is screwed on securely to maintain the vacuum seal and prevent accidental spills during transport.

What to consider before purchase

• Verify if the 0.5-liter capacity meets your daily hydration needs
• Check the dimensions to ensure it fits your preferred bag or cup holder
• Consider the intended use, as this model is optimized for personal, portable beverage storage

For optimal performance, we recommend hand-washing the flask with mild detergent and avoiding the use of abrasive sponges to preserve the integrity of the stainless steel surface and the vacuum seal.
