We think it’s important to do right by our planet with our products. At Iron Flask, we design our coffee mugs, tumblers, water bottles, and food jars from durable double-wall vacuum-insulated stainless steel that provides lifelong durability and hours-long temp control, so you never have to resort to single-use plastic again.
Tumblers & Mugs
People should enjoy their drinks at the perfect temperature, without spills. That’s why we craft our mugs and tumblers with double-wall vacuum insulation and premium stainless steel construction.
Iron Flask mugs and tumblers feature high-quality, 18/8 food-grade stainless steel that’s ultra-durable, easy to sanitize, and never rusts or leaves metallic flavors in your beverage. A powder-coated finish gives our stainless steel mugs and to-go cups a chic matte style and a damage-resistant, sweat-free exterior.
Nothing warms the soul like a sip of piping hot coffee when you need one—and the same goes for a cold iced tea or pisco sour. Iron Flask coffee mugs and tumblers deliver just that, every time, thanks to vacuum insulation between two walls of stainless steel. Iron Flask drinkware keeps your bevvie going strong, all day long.
Iron Flask tumblers and mugs come in all shapes and sizes, from the sleek Nomad to the curvy Rover, from the classic tumbler to the stout grip mug. Enjoy your beverage in a 12 oz, 16 oz, 24 oz, 28 oz, or 32 oz size, depending on your choice of coffee mug or tumbler.
Our stainless steel, insulated tumblers come with different lid and straw options, depending on the model. The Nomad will show up with a leak-proof flip lid, a splash-proof straw lid, and two plastic straws. The Rover includes a leak-proof flip lid and two separate plastic straws. The Rover 2.0 brings a leak-proof clear flip-top lid, a leak-proof straw lid and two plastic straws. The Classic comes with a press-in lid and two stainless steel straws, two plastic straws, and two straw-cleaning brushes. And our insulated grip mug features a leak-proof flip lid for easygoing sippin’. All lids and straws are BPA-free. Wash everything with warm soapy water to keep it in peak shape for the long haul.
We stand behind the quality of our insulated mugs and tumblers, and we offer customers a lifetime warranty and a 100% satisfaction guarantee on everything we make. Enjoy your drink while being nice to mother earth.
