The non-toxic, 100% leak-proof insulated Fellow thermos by AlpinTec is the ultimate universal choice for your daily hydration at the office, the gym, in the car, or on outdoor adventures. Designed with safety and elegance in mind, it offers one-handed opening with no fear of leaks, while also featuring a practical straw for comfortable and immediate use at any time of the day.

The biggest problem with ordinary stainless steel containers is definitively solved thanks to the innovative internal ceramic coating. As an inert and non-porous material, the ceramic surface does not react chemically with the contents, preventing coffee or tea residues from becoming trapped in the metal. The result is an absolutely clean taste with no metallic aftertaste, allowing you to enjoy your drink as if you were drinking it from a glass at home.

The combination of vacuum insulation and a ceramic coating ensures top-tier temperature stability: it keeps cold drinks cool for up to 24 hours (≤9°C at 12 hours) and hot drinks warm for up to 12 hours (≥50°C at 5 hours). At the same time, its smooth surface prevents stains from forming, making cleaning a breeze with a simple rinse and soap, without vigorous scrubbing.

With practical, ergonomic dimensions 6.5 x 8.5 x 18 cm and a capacity of 530ml (up to 600ml), it fits easily into most car cup holders and side bag pockets. It features an airtight folding lid that seals tightly. Hand washing is recommended to preserve the exterior and interior coating. Use by small children with hot beverages should always be under the direct supervision of an adult to prevent burns.
