The Iron Flask 18 oz Wide Mouth Water Bottle With Straw Lid has a sleek construction and wide range of colors which makes it easy on the eyes. But it’s not all about looks. This cup holder-friendly stainless steel water bottle has a double-wall vacuum-insulated design that ensures your drinks stay cold for 24 hours and hot for 12 hours, with no bottle sweat. We’ve included a flip lid and a stainless steel screw-on lid apart from the straw lid so you can swap them to suit your needs.
