  • Insulated design keeps water cold twice as long as uninsulated containers
  • Large mouth opening allows you to fill the flask easily with ice and drink mixes
  • Big Bite valve self-seals after each drink, eliminating annoying drips
  • Volume indicators in oz. and mm let you track hydration and electrolyte consumption
  • Hang the flask upside down for easy drainage and drying
  • All parts are top-rack dishwasher safe
