Plastic pollution in our oceans is an ever increasing problem, but we know how important it is to stay hydrated both on and off the water, which led us to develop this fantastic insulated steel water bottle. Made from high quality 316L marine grade stainless steel, the Red Original water bottle not only resists rust, but also won't corrode like other metal beverage bottles. Its corrosion resistant properties combined with the inherent strength and durability of steel ensure that any user will get years of use out of their bottle.
