Iron Flask started as a small company with a dream of providing the best sustainable water bottle out there. We launched in 2016 with little more than a vision of a better future and a healthier environment. We added a sleek, durable water bottle in a single size and color to that vision, and from there, we steadily expanded our selection. Today, we offer a range of elegant, cost-effective, eco-friendly products in a variety of colors and styles, and our line of plastic-bottle alternatives continues to grow.
We work hard to combat pollution with a better bottle—one that minimizes plastic waste and maximizes hydration.
We build our products to last a lifetime and maintain hot or cold temperatures for longer, so you can reduce, reuse, refill, and enjoy.
Iron Flask wouldn’t exist without the people who share our values. Through donations and partnerships, we promise to pay the goodwill forward and make a lasting and transformative impact.
We could talk about sustainability, quality, and community all day, but we’d rather walk the walk with our products. We use premium food-grade stainless steel and BPA-free plastic to craft bottles, tumblers, mugs, and food jars that will deliver great-tasting beverages and meals for years to come. We craft them with double-walled vacuum insulation, keeping those beverages and meals hotter or colder for hours and making an economical make-it-and-take-it approach more convenient.
