Water Bottles

Wide Mouth Straw Lid

Are you the kind that likes the easy-to-fill aspect of a wide mouth bottle but don’t necessarily want to drench your neck while drinking? The lid keeps things much more civilized.

About Iron Flask
We love helping people stay hydrated. That’s why we built our water bottles to be your sippin’ sidekick on every adventure. With premium stainless steel, double-wall vacuum insulation, and a range of features, sizes, and colors, Iron Flask water bottles will take your hydration game to the next level. Apart from the straw lid, this wide-mouth water bottle also comes with a flip-top lid and a leak-proof screw-on lid.
Stainless Steel Water Bottles
We craft our water bottles to stay in your life and out of the landfill. With top-quality 18/8 grade stainless steel that won’t impart a funky flavor and non-toxic, BPA-free plastic straw lids, Iron Flask wide mouth bottles are reusable and user-friendly. A matte powder-coated finish stands up to scuffs and scrapes.
Vacuum-Insulated Water Bottles
Double-wall vacuum insulation creates a virtual force-field around your drink, keeping it warm for up to 12 hours or cold for up to 24. Never lose a beverage to luke-warmness again.
Wide-Mouth Water Bottles
Wide-mouth water bottles have a large opening that makes them easy to clean and easy to fill with water or ice. You can chug straight from the wide-mouth opening or use one of the included lids for more control.
