The Steel Core Sling Thermos Cup ensures your beverages stay at their peak temperature, whether you're indoors or out in nature.

Its advanced insulation technology allows you to enjoy cold brews like cold泡茶 (cold-brew tea) and iced lattes without any condensation, and hot drinks like black coffee or herbal infusions stay warm even in chilly weather. Whether you're working from home or exploring the great outdoors, this thermos keeps your drink experience consistent and enjoyable.

More Than a Cup — A Lifestyle Choice

Choosing the Steel Core Sling Thermos Cup is more than just about keeping your drink warm or cold — it's about making a conscious decision to reduce single-use plastic waste and embrace a more sustainable way of living. With this reusable cup, you’re not only investing in a durable, stylish product but also contributing to a cleaner planet.

Available in a range of modern colors, it’s easy to find a style that matches your personality. Whether you're dressing it up for work or keeping it casual for a weekend trip, this thermos becomes an extension of your personal style — functional, fashionable, and forward-thinking.

Why Choose the Steel Core?

Not all thermos cups are created equal. The Steel Core Sling Thermos Cup stands out with its use of 304 stainless steel — a material known for its corrosion resistance, durability, and food-safe properties. Unlike cheaper alternatives that use lower-grade metals or thin insulation layers, this thermos ensures long-lasting performance and safety.

Real-world testing shows that it maintains heat for over 6 hours and keeps drinks cold for up to 24 hours, depending on the ambient temperature and initial drink temperature. It’s not just about the numbers — it’s about delivering consistent, reliable performance day after day.

To keep your thermos in top condition, simply rinse it after each use and occasionally give it a deeper clean with mild soap and water. Avoid using abrasive materials that could scratch the inner lining, and always ensure the lid is dry before sealing it again.

Make the Smart Choice Today

Whether you're a daily commuter, a dedicated student, a fitness lover, or someone who simply enjoys a great-tasting beverage, this thermos is designed to make your life easier and more enjoyable.
