Prometheus Design Werx AG Water Bottle

With a diameter of 3.60 inches, this bottle is wider than most standard automotive cup holders. It is designed primarily for external pack carry or securing to gear rather than fitting inside a vehicle console.

Yes, the wide-mouth opening is specifically designed to accommodate most standard water filtration systems, making it easy to fill directly from your filter in the field.

Thanks to the vacuum-sealed, copper-lined construction, you can expect cold beverages to stay chilled for 24 to 72 hours, while hot liquids will maintain their temperature for 12 to 18 hours, depending on ambient conditions.

The cap is designed to be fully leak-proof when tightened properly. The integrated leash also ensures you won't lose the cap while drinking on the trail, which is a common frustration with standard screw-top bottles.

The powder coat finish is textured specifically to enhance grip. It provides significant friction, making the bottle easy to handle even when wearing gloves or if your hands are wet.

The 18/8 food-grade stainless steel is non-reactive and does not retain flavors or odors. If you switch between coffee and water, a standard rinse is usually sufficient to keep the taste clean.
