Water Bottles

One Gallon

128 ounces of water equates to one gallon, a commonly recommended daily hydration goal. With our 1 gallon water bottle, you can achieve your H2O dream with just one bottle fill.

About Iron Flask

Wherever you’re headed, you need to stay hydrated—that’s why Iron Flask designed its water bottles to accompany you on every adventure. With premium stainless steel, double-wall vacuum insulation, a slew of handy features, and a range of sizes and colors, our water bottles make beverage management a breeze.

Stainless Steel Water Bottles

We construct our water bottles with high-quality stainless steel and non-toxic, BPA-free plastic lids. Unlike single-use plastic bottles which pile up in landfills, our water bottles are durable, reusable, and eco-friendly. A powder-coated finish lends a hip matte look and stands up to day-to-day scuffs and scrapes.

Vacuum-Insulated Water Bottles

Double-wall vacuum insulation keeps liquids warm for up to 12 hours and cold for up to 24 hours. No more cold coffee or warm water (unless that’s what you’re going for).

Water Bottle Lids & Accessories

This 1 gallon stainless steel water bottle comes with a leak-proof screw-on spout lid with a comfy carry handle, so you won’t waste a drop of H20. And be sure to check out Iron Flask water bottle accessories, which include cleaning brushes to keep your bottle looking as fresh as its water tastes.

Water Bottle Warranty

Iron Flask stands behind the quality of our products, and we offer customers a lifetime warranty against manufacturing defects and a 100% satisfaction guarantee on everything we make. Reduce plastic waste. Stay hydrated. Look good doing it.
