Ice cubes from standard refrigerator/freezer door ice dispensers fit perfectly through the standard mouth.
Our water bottles were developed to perform in every environment. Each HydroFlask is hand cast from double wall vacuum insulated food grade 18/8 stainless steel, therefore they are BPA-Free and resistant to bacteria and odors. Our double wall vacuum insulation technology allows Hydro Flasks to keep contents hot for 12 hours and cold for 24 hours. Look for the silver ring on the neck of every Standard Mouth HydroFlask to ensure you're getting the best performing water bottle on the market.
