350ml Outdoor Camping Sports Double Wall Stainless Steel Insulated Vacuum Flask Beer Cola Tumbler

Design Innovation
Ergonomic Shape
Our design team has meticulously crafted the tumbler with an ergonomic shape in mind. The contoured body fits snugly in your hand, providing a comfortable grip that won’t slip even when your hands are wet or sweaty. The wider base ensures stability when placed on uneven surfaces like picnic tables or rocky terrain, preventing accidental spills. This thoughtful design consideration makes it incredibly user-friendly, whether you’re a seasoned outdoor enthusiast or a casual user.

Unique Double Wall Construction
The double wall design is the heart of our tumbler’s innovation. Unlike traditional single-wall tumblers, our double wall construction creates an insulating barrier that effectively traps heat or cold, maintaining your beverage’s temperature for an extended period. The inner and outer walls are expertly welded together, creating a vacuum seal that minimizes heat transfer. This not only keeps your drinks hot or cold but also prevents condensation from forming on the exterior, ensuring your tumbler remains dry and easy to handle.

Customizable Engravings
We understand that personalization is key. That’s why we offer customizable engraving options on the tumbler. You can choose to have your name, initials, or a special message engraved on the surface. This not only adds a personal touch but also makes it a great gift for friends, family, or colleagues. The engraving process uses state-of-the-art laser technology, ensuring a precise and durable finish that won’t fade or wear off over time.

Sleek and Stylish Aesthetics
In terms of aesthetics, our tumbler stands out from the crowd. The sleek, modern design with a matte finish gives it a sophisticated look that complements any setting. The 350ml capacity is the perfect size – not too bulky to carry around, yet large enough to hold a satisfying amount of your favorite drink. The combination of functionality and style makes it a must-have accessory for any outdoor adventure or daily use.

Manufacturing Precision
High-Quality Stainless Steel
We source only the finest stainless steel for our tumblers. The steel used is of the highest grade, ensuring durability, rust resistance, and longevity. It’s also 100% BPA-free, so you can enjoy your drinks without worrying about harmful chemicals leaching into them. The stainless steel is carefully selected for its ability to withstand extreme temperatures, making it ideal for both hot and cold beverages.

Precision Welding
The double wall construction requires precise welding to create the vacuum seal. Our skilled technicians use advanced welding techniques and state-of-the-art equipment to ensure each weld is perfect. The welding process is closely monitored to guarantee there are no leaks or imperfections in the vacuum seal. This attention to detail ensures that the insulation properties of the tumbler remain intact, providing consistent temperature retention for your drinks.

Rigorous Quality Control
Every tumbler goes through a rigorous quality control process before it leaves our manufacturing facility. Our quality control team inspects each tumbler for any defects, such as scratches, dents, or imperfections in the welding. They also conduct temperature retention tests to ensure that the tumbler meets our high standards. Only tumblers that pass all these tests with flying colors are packaged and shipped to our customers.

Leak-Proof Lid
The lid of our tumbler is designed with a leak-proof seal in mind. It features a food-grade silicone gasket that creates an airtight seal when the lid is screwed on. The gasket is carefully selected for its durability and resistance to wear and tear. The lid is also designed to be easy to open and close, with a smooth twist action. Before packaging, each lid is tested for its leak-proof capabilities to ensure that your drinks stay securely inside, even when the tumbler is tilted or turned upside down.

Features
Insulation Capabilities
Thanks to the double wall vacuum insulation, your hot drinks will stay hot for up to 8 hours, while your cold beverages will remain cold for up to 12 hours. This means you can enjoy a steaming cup of coffee in the morning and a refreshing cold beer or cola in the evening, all from the same tumbler.

Wide Mouth Opening
The wide mouth opening of the tumbler makes it incredibly easy to add ice cubes, fruits, or other ingredients to your drinks. It also allows for hassle-fre

e cleaning. You can easily reach the inside with a bottle brush or even put it in the dishwasher for a thorough clean. The wide opening also makes it compatible with most standard water filters, so you can enjoy purified water on the go.

It’s lightweight, so it won’t weigh you down when you’re on the move. The tumbler also comes with a convenient carrying handle, allowing you to easily attach it to your backpack or belt loop.
