Narrow Mouth Spout Lid

Hydration is the name of our game, and we design our water bottles to up your game. With premium stainless steel, double-wall vacuum insulation, and features, sizes, and colors galore, we take beverage management seriously. Apart from the spout lid, you’ll also find a flip-top lid and a leak-proof screw-on lid with a carry handle in the box.

We craft our water bottles to beat the pants off plastic water bottles. With 18/8-grade powder-coated stainless steel that lasts a really long time and won’t transfer flavor to your beverage, Iron Flask narrow-mouth bottles are a solid (and stylish) choice.

Double-wall vacuum insulation wraps your drink in a layer of near-nothingness, preventing heat transfer from inside and out. This means warm drinks stay warm for up to 12 hours or cold ones stay cold for up to 24.

Narrow-mouth water bottles have a smaller opening, so you won’t douse yourself while taking a drink. You can also use one of the three included lids to customize your bottle based on your activity.

At Iron Flask, we stand behind the quality of our products with a lifetime warranty against manufacturing defects and a 100% satisfaction guarantee on all of our products. We don’t like plastic, but we love you!
