With the tremendous popularity of our "industry standard wide mouth," We have decided to add another new member to the Hydro Flask family; The 18oz Wide Mouth! All of the same great features you have come to expect from the wide mouth now in a compact, easy to carry size!
Our water bottles were developed to perform in every environment. Each Hydro Flask 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.
