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.
Narrow-mouth water bottles have a smaller opening than wide-mouth bottles, so the flow to your mouth happens at a more controlled rate. That means a smaller chance of spilling on your outfit.
