Iron Flask makes water bottles, mugs, and tumblers that make hydration and caffeination a sustainable and convenient experience—extra convenient when you expand your lid collection or outfit your bottle with a protective boot. Level up your bottle and keep it in prime condition for unlimited use.
Your Iron Flask water bottle is a work of art. And with our accessories, you can keep your prized possession sparkling clean, scuff-free, and in tip-top shape for years to come.
Shop for spout lid sets specifically for Iron Flask narrow mouth or wide mouth water bottles, and always have a water bottle lid on hand—even if you lose one or the dishwasher is taking FOREVER.
Iron Flask straw lid sets include straw-cleaning brushes to keep your straw sparkling clean and sipping like new. You can also pick up one of our bottle-cleaning brushes to help sanitize every inch of your Iron Flask water bottle, mug, tumbler, or food jar.
Iron Flask went all out with its Paracord Carry Handle, made from sturdy yet flexible kernmantle rope. If it’s good enough for astronauts, we figure it’s good enough for our wide mouth water bottles. This handle is water-proof and super durable, and it includes a carabiner, a fire starter, a compass, and whistle, so fill your bottle and get out there!
Iron Flask water bottle protective boots come in two sizes to fit 12–24 oz and 32–64 oz water bottles. These silicone sleeves act as insulation boosters, built-in coasters, no-slip grips, and bottle-base protectors all in one. They’re sleek, flexible, and snug, and they’ll help keep your bottle living its best life.
We stand behind the quality of our products, and we offer customers a lifetime warranty and a 100% satisfaction guarantee on everything we make. Less plastic and more hydration!
