Stanley The Iceflow Aerolight 36oz Water Bottle Fast Flow

Good for a trip to the gym or a day at the office, Stanley's The IceFlow Aerolight 36oz Water Bottle with the Fast Flow Lid is lighter than standard stainless steel tumblers while still providing heavy duty insulation that keeps our drinks cold for 15 hours and iced for 3 days. The double-wall vacuum insulation maintains a wintry environment inside the bottle, while the wide-mouth Fast Flow Lid makes for easy drinking, pouring, and cleaning.
