The only 40oz Tumbler you will ever need! Double insulated to keep your drinks ice cold for up to 24 hours, this tumbler features two reusable straws (one standard and one jumbo) to switch from water to smoothies with ease. The twist on, easy grip lid features a splash proof gasket that seals snug around the straws so that you're free from spills.   Designed to be cupholder friendly, the base is protected with a silicone bumper to prevent dents and ensure a quiet set down. The ergonomic handle can be comfortably carried from kitchen to car. Dishwasher safe (lid and cup), the wide mouth makes it easy to clean and to fill.   Keep your cold brew, herbal tea, or iced macha frosty for up to 24 hours with sweat-free double-wall.
