Iron Flask designs its water bottles to combine form and function. We like to think that people come for the colors and patterns, and stay for the craftsmanship, which includes premium stainless steel, double-wall vacuum insulation, and a range of features and sizes. Our narrow-mouth water bottles come in straw-lid and spout-lid versions, and regardless of which version you choose, you’ll find a flip-top lid and a leak-proof screw-on lid with a handle in the box as well. The 12, 16, 20 and 24 oz narrow mouth water bottle sizes fit nicely in almost any cup holder, but we also offer larger sizes for those who’d rather have tons of water.

Carrying an Iron Flask water bottle screams good taste—and not just because of their eye-catching colors and patterns. They also happen to be made from 18/8-grade stainless steel that won’t transfer flavor to your beverage (or single-use plastic trash to the landfill).

Whether you’re toting ice-cold water or boiling hot tea, double-wall vacuum insulation protects your liquid from heat transfer, keeping that water cold for up to 24 hours and that tea hot for up to 12.

Use one of the three included lids to suit your bottle to the moment’s need. Want your narrow-mouth bottle to live its best life? Check out our water bottle accessories like protective boots, cleaning brushes, and more.
