Water Bottles

Wide Mouth

Wide-mouth water bottles are easy to fill, easy to add ice to, and easy to clean. And if you’re more of a gulper or a chugger than a sipper, the wide-mouth opening may be the right choice for you.

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. Our wide-mouth water bottles come with three different lids in the box: a straw lid or a spout lid, a flip lid with a handle, and a stainless steel screw-on lid, so you can switch them up however you like. The 14, 18 and 22 oz wide-mouth water bottle sizes fit nicely in almost any cup holder, but we also offer larger sizes in case your priority is having lots of water.

Stainless Steel Water Bottles

We construct our wide-mouth water bottles with high-quality stainless steel and non-toxic, BPA-free plastic lids. While single-use plastic bottles accumulate in oceans and landfills, Iron Flask stainless steel water bottles are reusable and made to last a lifetime. We finish them off with a matte, powder-coated finish for extra style points and durability.

Vacuum-Insulated Water Bottles

Double-wall vacuum insulation prevents heat transfer, keeping your drink warm for up to 12 hours or cold for up to 24. Water, sports drink, coffee, chocolate milk—whatever you like, at the temperature you like.

Water Bottle Lids & Accessories

Don’t miss out on Iron Flask water bottle accessories like paracord handles, protective boots, and cleaning brushes to keep your bottle in tip-top shape.

Water Bottle Warranty

Iron Flask is committed to making high-quality water bottles and we offer customers a lifetime warranty against manufacturing defects and a 100% satisfaction guarantee on all of our products, just to make sure you absolutely love your Iron Flask goodies.
