Single-use plastic is terrible for the environment, and even if you recycle plastic bottles, only 8% are converted into an equally usable product.

If you care about the environment, investing in the best gallon water bottle or another size Iron Flask is a great way to say no to the plastic industry.

Every time you use your reusable Iron Flask water bottle, you can feel good that you're not participating in the consumption of common single-use plastics which have a life cycle that is bad for the environment from start to finish.

5. Functional Built-in Features

The Iron Flask was designed to be the best travel water bottle, which is why the different models are built with integrated handles on the lids. The useful built-in handle gives you an easy grip along with additional storage options when you're on the move. With the included carabiner, you can easily clip the handle lid onto loops on your backpack or other gear. Or use the handle lid for easy access and a secure grip when you're holding it in your hand.

Many of the Iron Flask models also have a cup-holder-friendly design, giving you even more storage options when you’re out and about. Easily keep your bottle secured in your car, bicycle, backpack, or other common places with built-in cup holders.

6. Premium Materials

Iron Flask makes the best reusable water bottle using premium materials like double-walled vacuum insulated stainless steel. This advanced technology helps keep drinks hot or cold for hours, allowing you to enjoy your beverages at exactly the right temperature. Our bottle’s stainless steel body is ultra-durable, lightweight, and easy to carry.

Stainless steel is also non-toxic and doesn't have any flavor transfer, so your drinks will taste exactly as they should. Good water bottles are also easy to clean, as stainless steel never rusts and can be sanitized with a bottle brush and hot, soapy water. Still need a reason for why we know Iron Flask is the best reusable water bottle? Our BPA-free plastic lids and straws are safe to use and dependable for the long haul.

The BPA-free silicone gives it a steady and secure placement, working as a built-in coaster. Another benefit is the streamlined design that fits easily into most cup holders and keeps the area clean.

9. Save Money

There are many reasons to use the best insulated water bottle from Iron Flask instead of the plastic variety. Not only is it terrible for the environment, but it's also expensive, especially if you depend on it as your main source of hydration.

When you do the math, an Iron Flask water bottle is a great investment that will save you money in the long term. While it might not seem that significant on a day-to-day basis, the savings over the months and years is huge. In fact, researchers from Penn State University found that the average individual can save $1,236 per year and $6,180 over five years by ditching single-use plastic water bottles; a family of four can save $123,000 over five years.

By not being part of the plastic bottle sales funnel, you’re also reducing the amount of trash that cities and local governments will need to recycle or incinerate. Consequently, a reduction in plastic waste can impact the economy in a positive way with an increase in wages, sales, and goods and services.

10. It’s Better for Your Health

Plastic bottles might be convenient when you need fast hydration on the go, but the reusable stainless steel variety is non-toxic and chemical-free, making it the better option for both your health and the planet. The problem with plastic bottles is that they contain BPA, a common chemical found in single-use plastic. Many studies have documented the dangers of BPA, including links to infertility and metabolic disease.

There are many reasons why Iron Flask is considered the best water bottle by many happy customers. Along with a long list of top-rated features that are built to last and perform like no other, you can also expect the most affordable price — making Iron Flask the best insulated water bottle brand out there.
