Prometheus Design Werx FT Water Bottle

The fluted design serves two practical functions: it increases the structural rigidity of the stainless steel shell to withstand impacts and provides a tactile, non-slip grip that is easier to hold when your hands are wet or gloved.

With a diameter of 3.60 inches, this bottle is wider than most standard automotive cup holders. It is best suited for carrying in a backpack side pocket or securing to the outside of your pack.

The bottle comes with two interchangeable caps, allowing you to switch between different drinking styles depending on your activity. This versatility makes it easy to adapt the bottle for both rugged backcountry use and everyday commuting.

Yes, the wide-mouth opening is designed to accommodate most standard water filtration systems, making it a convenient choice for hiking and camping trips where you need to refill from natural sources.

Thanks to the vacuum-sealed double-wall construction and copper lining, you can expect cold retention between 24 and 72 hours and hot retention between 12 and 18 hours, depending on the ambient temperature and how often the bottle is opened.

Yes, the bottle is constructed from food-grade 18/8 stainless steel and is completely BPA-free, ensuring that it won't leach chemicals or retain flavors from previous beverages.
