Additional Information

About Iron Flask

From the concrete jungle to the great outdoors, Iron Flask makes it easy to bring your bevvie along for the ride. We designed our water bottles to keep up with active lifestyles—that means premium stainless steel, double-wall vacuum insulation, eye-popping colors, and a range of functional features. Sizes range from 12 to 128 oz.

Stainless Steel Water Bottles

Iron Flask water bottles feature high-quality stainless steel with non-toxic, BPA-free plastic lids. They’re an awesome alternative to single-use plastic bottles, which hurt the environment and can literally leave a bad taste in your mouth. A powder-coated finish gives these flask water bottles a modern matte look that holds up to everyday wear and tear.

Vacuum-Insulated Water Bottles

Double-wall vacuum insulation keeps liquids warm for up to 12 hours and cold for up to 24 hours. With Iron Flask, all you taste is your drink, at the temperature you want to drink it. Here’s to piping hot coffee and ice-cold water on the go.

Water Bottle Shapes & Sizes

Our 14 oz, 18 oz, and 22 oz water bottles are cup holder-friendly, but they also come in 32 oz, 40 oz, and 64 oz versions if you need a bigger bottle.
Be sure to check out our best-selling wide-mouth water bottles—their wide mouth makes them easy to fill-up and they come with three different leak-proof lids for you to switch from. The 14 oz, 18 oz and 22 oz versions fit into most car, bike, and backpack cup holders, or you can opt for the larger 32 oz, 40 oz, 64 oz and one-gallon bottles if you need lots of water.

Water Bottle Lids & Accessories

Our wide mouth and narrow mouth water bottles come with a straw lid or a spout lid, plus two additional lids at no extra cost, so you can choose the right top for the activity at hand. The straw lid delivers cold water or a refreshing sports drink right to your mouth in the most sophisticated way—no squeezing or neck-craning required. The spout lid provides a quicker quench on the go. Both feature a 100% leak-proof design. Whether you choose a straw–lid or spout-lid bottle, you’ll also get a bomb-proof stainless steel screw-on lid and a flip-lid with a slip-free handle for care-free carrying.

Our accessories, which include paracord handles, extra lids, and cleaning brushes, ensure you’ll get the most out of your Iron Flask water bottle. We also offer a protective boot which fits 12 oz- 24 oz bottles, and a larger boot for the 32 oz- 64 oz sizes.
