These bold, colourful tumblers are made to keep you hydrated in a fully functional style. Ideal for car commutes or workouts at home, it has a built-in flip straw for easy and effortless sipping. Snap it shut and the double-wall vacuum insulation will keep your drink extra cold for hours. It fits comfortably in your vehicle’s cup holder (treadmills and spin cycles, too!), and the folding handle lets you quickly grab and go. To help you live a sustainable lifestyle, the IceFlow Tumbler is made in part from recycled plastics sourced from discarded fishing nets, sparing our waters of plastic waste.
