Perfect for outdoor adventures, family picnics, camping trips, long road journeys, or demanding workdays, this high-performance vacuum flask ensures your beverages stay at the perfect temperature whenever you need them. Powered by Thermos’ renowned double-wall vacuum insulation technology, the flask creates an airless thermal barrier that locks in temperature and keeps drinks hot or cold for up to 24 hours, making it ideal for carrying coffee, tea, hot chocolate, soup, chilled water, or refreshing cold beverages. Its rugged matte black stainless steel exterior offers a bold, professional look while also providing durability against everyday wear and outdoor conditions. With a generous 1.2L capacity, this flask provides ample beverage storage for sharing or long hours away from home, while its balanced cylindrical design with dimensions of 9.5 x 10.5 x 31.0 cm ensures it remains practical to store in backpacks, travel bags, or camping gear.

Constructed from premium stainless steel both inside and out, the Thermos Stainless King Flask is engineered to withstand daily use, accidental drops, and demanding surroundings without compromising performance. The tough stainless steel body resists rust, corrosion, and flavor retention, helping preserve the natural taste of your beverages over time. Designed with convenience in mind, the flask features a precision twist-and-pour stopper that allows you to pour beverages smoothly without removing the stopper completely, reducing heat loss and maintaining optimal temperature retention while serving. The built-in insulated stainless steel serving cup doubles as a drinking cup, remaining cool to the touch for comfortable use and conveniently storing back onto the flask for compact portability. A fold-away handle provides easy carrying during travel and ensures a secure grip when pouring drinks, enhancing stability and preventing spills. With a durable structure and a weight of 670g, this flask balances strength and portability while delivering reliable performance for both everyday use and outdoor activities.
