Narrow Mouth Spout Lid

Narrow mouth spout lid water bottles make it easy to knock back a big swig with confidence, and they come with a handle so you can take it with you wherever the day takes you. 

About Iron Flask

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.

Stainless Steel Water Bottles

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.

Vacuum-Insulated Water Bottles

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

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.
