Sip your favorite beverage at the temperature the drink gods intended thanks to the double-wall vacuum insulation of the Iron Flask 40 oz Water Bottle With Straw Lid— 24 hours of icy coldness and 12 hours of piping hotness while staying sweat-proof. This bottle can stand up to roughhousing, but it’s not just another big, dumb water bottle. It features a wide mouth and a carabiner straw lid for quick filling and spill-proof sipping on the go, plus a flip lid and a stainless steel screw-on lid for more options.
