ThermoFlask 24 oz Insulated Stainless Steel Straw Tumbler, Onyx

Introducing our best-insulated tumbler for cold drinks, the Stay Cool. This 24 ounce vacuum insulated tumbler is designed to offer you effortless access to ice-cold refreshment all day long, keeping drinks perfectly chilled for up to 24 hours. The straw lid provides refreshment with one hand and no need to tilt the tumbler. The wide mouth of the lid makes it easy to clean the tumbler. Perfect for a hike, run, yoga session, or workout at the gym when you need that hit of ice-cold hydration the most.

The double-wall insulation of this water tumbler does more than simply keep the contents cold, it also acts as a buffer to prevent condensation, making the outside of the tumbler sweat-free and easy to hold onto. The tumbler is made from food-grade stainless steel, is BPA-free and toxin-free, so you can refill it for years to come with the utmost confidence. The slim tumbler fits into most cup holders and won’t take up too much space in your backpack, so you can easily carry your bottle anywhere you go.
