The Stanley water bottles are perfect for the day: the Quencher H2.O FlowState with handle and straw, the IceFlow with foldable straw or Fast Flow, the Wellspring, the All Day, the AeroLight for travel, the Vitalize shaker, and the Everyday camping mug.
Their vacuum insulation, sandwiched between two steel walls, keeps water cold or tea hot for hours. The Quencher fits into most car cup holders; the IceFlow slips into a sports bag.
Rinse them after use and wash the straws and lids separately.
The story of the steel bottle is told on the Stanley page. Other brands can be found in the women's accessories by brand.
