Hydro Flask 621ml Standard Flex Straw Cap

TempShield™: TempShield™ insulation technology, a key feature of Hydro Flask products, in a neutral style. Advanced double-wall vacuum insulation technology that leads the way in keeping beverages thermoregulated. The design involves creating an airtight space between two layers of stainless steel, virtually eliminating heat transfer through conduction and flow. This innovation allows drinks to be kept ice cold for up to 24 hours or hot for up to 12 hours. TempShield™ technology also features the elimination of condensation on the outer surface (called dew point) and the prevention of temperature transfer to the outer wall, so the container remains safe and dry to the touch at all times.

Stainless steel: Premium alloy of iron, chromium, and other elements, valued for its exceptional durability and aesthetic appearance. In footwear accessories and details, it stands out for its hardness, which prevents deformation and offers high scratch resistance. Its main advantage is corrosion resistance—it does not react to sweat or moisture, maintaining its shine and color even after years of wear. This material is also hypoallergenic, making it ideal for jewelry and parts of products that come into direct contact with the skin. It is a symbol of quality, strength, and timeless design.
