JIAKANGCUP 1100 ML Double-Wall Insulated Steel Vacuum Flask

The JIAKANGCUP vacuum flask has a generous capacity of 1100 ML — significantly larger than standard 500–750 ML flasks — making it ideal for people who need to stay hydrated throughout a long workday, gym session, school day, commute, hike, or travel journey without frequent refilling. Double-wall insulation refers to the construction of the flask body, which has two separate stainless steel walls with a vacuum-sealed gap between them. This vacuum gap eliminates heat transfer between the inside of the flask and the outside environment, meaning hot beverages such as tea or coffee stay hot for hours and cold beverages such as chilled water or juice stay cold for an extended period. The vacuum gap between the walls also prevents condensation from forming on the exterior surface of the flask, keeping your hands and bag dry during use.

The JIAKANGCUP 1100 ML vacuum flask is available in four colour finishes — White, Black, Blue, and Red — all at the same price with identical features and specifications. White is the cleanest and most minimal option, complementing any bag, desk, or lifestyle aesthetic without drawing attention to itself. Black is bold, sleek, and contemporary — a timeless everyday carry colour that suits professional and casual use equally well and shows fewer marks with daily use. Blue is fresh and energetic, making it a popular choice for gym, outdoor, and active travel use where a sportier aesthetic is preferred. Red is the most vibrant and eye-catching of the four, ideal for anyone who wants their flask to stand out and be easily identifiable in a gym bag, locker, or crowded setting. All four colours are equally durable and offer the same double-wall insulation performance.

The JIAKANGCUP 1100 ML vacuum flask is suitable for a wide range of hot and cold beverages. For hot beverages, it works excellently for doodh pati chai, green tea, black tea, herbal infusions, filter coffee, Americano, and any other hot drink you want to keep warm for hours while on the go. For cold beverages, the double-wall insulation keeps cold water, chilled juices, lemon water, infused fruit water, iced tea, and cold protein shakes at a refreshingly cool temperature for extended periods, making the flask particularly well-suited for gym sessions, outdoor activities, and long commutes in warm weather. The 1100 ML capacity means you can carry a full day’s hydration in a single flask, and the straw lid with sucking top makes it easy to sip any beverage conveniently without tilting or fully opening the flask.

For best results and long-lasting hygiene, we recommend hand washing the JIAKANGCUP vacuum flask after every use. Rinse the interior with warm water and use a long bottle brush with mild dish soap to clean the inside of the flask body thoroughly, paying particular attention to the base of the interior where beverage residue tends to settle. For the straw lid and straw, use a dedicated straw cleaning brush to clean the interior of the straw and the lid components with warm soapy water, then rinse all parts thoroughly. Allow all components — the flask body, lid, and straw — to air dry completely with the lid open before reassembling and storing to prevent moisture build-up and odour development inside the flask. For the soft cloth handle, hand wash gently with mild soap and water and allow to air dry. Avoid putting the flask in a dishwasher, as high heat and harsh dishwasher detergents may degrade the vacuum insulation seal and the exterior finish over time.

Absolutely — the JIAKANGCUP 1100 ML vacuum flask is one of the most universally practical and immediately appreciated gifting options in the Kaka Bawa Sons drinkware range. A high-quality insulated flask is something virtually everyone uses daily, and the combination of a generous 1100 ML capacity, reliable double-wall vacuum insulation, a convenient straw lid for on-the-go sipping, a comfortable soft cloth handle, and a choice of four colour finishes — White, Black, Blue, and Red — makes this a genuinely thoughtful and personalised gift that the recipient will reach for every single day. It is an especially well-suited gift for students who carry it to school or university, professionals who use it at their desk or during commutes, gym-goers who need a large-capacity hydration flask for workouts, hikers and outdoor enthusiasts, and frequent travellers. A practical, durable, and daily-use gift that is always appreciated.
