How long will this bottle keep drinks cold?

The bottle uses Hydro Flask’s TempShield double-wall vacuum insulation to maintain beverage temperature. Expect chilled drinks to stay cold throughout a full day of activity and iced beverages to retain ice for extended periods.

Is the Flex Straw Cap truly leakproof and easy to use?

• Soft, flexible straw for comfortable sipping on the go.

• Stainless steel interior prevents lingering tastes and odors.
• Detachable straw and lid components for deep cleaning.
• Dishwasher-safe parts help keep the finish bright and sanitary.
