Enjoy sparkling water, sodas, or refreshing beer wherever you go with this innovative 600 ml stainless steel cool tumbler, finished in a classic dark blue. Specially engineered to safely accommodate fizzy drinks, the opening features unique safety pressure-release grooves within the cap threads that slowly vent built-up gas as you unscrew it. 

The interior is treated with an ultra-smooth mirror-finish structure, a specialized coating that minimizes surface friction to keep carbonation from fizzing out prematurely. 

Designed for effortless daily maintenance, the upper section of the tumbler completely detaches, creating an extra-wide opening that lets you easily drop in large ice cubes and allows thorough cleaning.

With its thoughtful, multi-part design, your favourite carbonated drinks stay bubbly and fresh, making it easy to enjoy while working, outdoors, or on the go.
