These vibrant tumblers are designed to keep you hydrated in a practical way. Perfect for car rides or home workouts, it features a built-in flip straw for simple, hassle-free sipping. Close it, and the double-wall vacuum insulation ensures your drink stays fully leakproof and icy cold for hours. It fits snugly in your vehicle's cup holder (and on treadmills too!), with a folding handle for quick grab-and-go. To support a sustainable lifestyle, the IceFlow Tumbler is partly made from recycled plastics sourced from discarded fishing nets, helping to reduce plastic waste in our waters.
