Iron Flask has done a good job of producing affordable water bottles with some very workable designs and quality.
The Iron Flask Water Bottle can keep your coffee hot for hours and your iced drink cold for over a day. The wide mouth design with 3 different lids, including a straw top, make it a bit of a favorite for some of our staff.
After a couple of years of testing this bottle on and off, we have a pretty good idea of what it can and cannot do. Iron Flask is now one of the most popular water bottles and the price reflects this demand.

Modern design meets functionality.
The first impression of this stainless steel water bottle is that the box is impressive and the feel of it all is nice too. It’s immediately apparent why this is a popular item.
Iron Flask is currently available in six sizes: 14 oz., 18 oz., 22 oz., 32 oz., 40 oz., and 64 oz. You can grab them in colorful variations. You choose from cotton candy, aquamarine, bubblegum, dark rainbow, fire, fire red, kiwi green, midnight black, peach, sky, and twilight blue (we most love the hues of dark rainbow!).
The ones between 14 oz. and 22 oz. are the best for your daily use. Sneak it in your backpack’s water bottle holder and let them sit in your car’s cup holder, no problem. The big tumblers over 22 oz. are ideal for the outdoors.
If you know you won’t have any water source nearby, they’re your best option. But if you hate adding extra weight to your journey, you can take a look at Brita Premium Filtering Water Bottle as an alternative.
Double-wall insulation allows Iron Flask to keep your cold beverage ice-cold for 18-24 hours. We dropped some ice cubes inside, and they stayed whole until the following day! That’s way better than YETI Rambler Water Bottle’s capacity! Your beloved cappuccino will remain hot for up to 10-12 hours as well. Iron Flask will be a wise choice if you like taking coffee to work.
Because of the wide mouth, Iron Flask is great as a food thermos. These Eggs Benedict had hot Hollandaise on them, thanks to the Iron Flask, which kept the sauce warm for an hour without any leaks.
Even though Iron Flask’s straw lid is the only one with a carrying handle, the powder coating of this tumbler makes the vessel of 22 oz. and smaller bottles easy to carry. But if you want to stay hands-free, you’ll benefit from getting a CONTIGO Autoseal Chill Water Bottle or Takeya 24 oz. Originals Insulated Water Bottle.
Iron Flask won’t let you down with its performance. The modern design didn’t compromise its functionality.
It’s a steal for anyone looking for a durable water bottle with a sleek look.
- Material:: 18/8 stainless steel
- Available in:: 14 oz., 18 oz., 22 oz., 32 oz., 40 oz., and 64 oz.
- Available colors: : cotton candy, aquamarine, bubblegum, dark rainbow, fire, fire red, kiwi green, midnight black, peach, sky, and twilight blue
A Reliable Flask?
Do you like bringing your coffee for your mid-day break at work? Iron Flask can keep it warm for you for up to unlit lunchtime! Your ice-cold drink will stay chilled for more than a day! Pour in some ice cubes for more chilliness. You can expect that even after an overnight stay in Sedona grounds, you’ll have a refreshing drink the following afternoon.
It’s also an affordable alternative if you’re tight on budget. Iron Flask found the sweet point between price and quality.
But if you’re looking for a water bottle with proper water intake in mind, using Iron Flask can be counterproductive. It will tempt you to chug up flavored drinks, whether it’s hot or cold. A basic tumbler like Nalgene Wide Mouth Water Bottle is a good option. It will restrict you to water only with its lack of insulation.
You can count on Iron Flask to satisfy your thirst. It’s a must-have whether you’re in the bustling downtown or venturing past beyond the shores for some fishing escapade.

How does it compare to other water bottles?
Iron Flask Water Bottle is 18/8 pro-grade stainless steel made. It’s a common material used for water bottles with double-wall insulation. Hydro Flask, Yeti, Klean Kanteen, Cirkul, and TAKEYA also have their stainless steel tumblers. Health-wise, it’s safe (BPA-free), rust-resistant, and doesn’t add any metal taste to your drink. Although, this material is notorious for denting.
It won’t wear out quickly compared to a cheap plastic water bottle and doesn’t have any plastic taste to your beverage.
This tumbler from Iron Flask is also very easy to use. No matter which cap you choose for the day, drinking is easy-peasy. The carabiner straw and flip lid are accessible within your fingertips. Both offer you controlled flow with every chug. The stainless steel lid opens when you unscrew it counterclockwise. Be mindful you might tilt it too quickly and end up pouring everything on yourself.
These options are Iron Flask’s extra edge over water bottles that only come in with a single lid. It’s like getting Hydro Flask’s 16 oz. Wide Mouth’s sip lid and Thermoflask Double Stainless Steel Insulated Water Bottle’s straw lid. Plus, Nalgene’s wide mouth screw lid. All in one package!
But keep in mind that only the straw lid of Iron Flask has a carrying handle. It’s solid and carabiner-friendly, serving you with a comfortable 2-finger grip. The other caps don’t have any handles. You’ll either place them inside your backpack or carry them by vessel. It’s powder-coated anyway, so you won’t have a hard time holding it.
Unless you have the bigger bottles, then you won’t have any trouble. If you focus on a comfy handle, Hydro Flask’s Flex Handle won’t let you down.
Now, let’s talk about maintenance. Iron Flask doesn’t need any special cleaner like Brita Premium Filtering Water Bottle. But, it’s not dishwasher-safe as YETI Rambler Water Bottle or CONTIGO Autoseal Chill Water Bottle is. Hand washing Iron Flask is relatively a breeze anyway. To clean your bottle use soap with hot water to avoid damaging its powder coating. No need to dismantle anything like how you would with a Hydro Flask 16 oz. Wide Mouth with Sip Lid.
Overall, Iron Flask is one of the best and most affordable tumblers out there. Just a carrying handle could be of use with it.
Conclusion
With a budget-friendly price range ($22 – $30), Iron Flask returns your investment in spades. You get durability and reliability.
It serves its purpose. Although, you need extra caution with its maintenance since the powder-coating is delicate.
It’s cheaper than the competitor Hydro Flask 24 oz. Standard Mouth (roughly $35) with almost the same quality.
Bonus, you get three lids for what you paid in a single purchase!
For some reason, your Iron Flask ended up damaged? They have a lifetime warranty to cover you.
There’s an Iron Flask for you whether you plan to take it to the office or on a weekend camping trip.

Frequently asked questions
Iron Flask is made in the People’s Republic of China.
It is common for stainless steel water bottles. Even American brands like Hydro Flask, Takeya, Klean Kanteen, CONTIGO, and Cirkul are all China-made. Manufacturing this product in the US will double the production cost, making it impossible to market.
And no, they don’t bear the stereotypical low-quality misconception of “Made in China” items. No worries about its build.
Your Iron Flask’s powder-coating is the main reason why your tumbler can’t go inside your dishwasher. The entire process and high temperature are brutal on the coating.
Instead, gently brush your iron Flask and clean it using hot water with soap. Now, if you notice spots inside the bottle (stainless steel is rust-resistant anyway), you can put distilled vinegar and shake it for 10 minutes. If that extra effort still didn’t work, use water with baking soda while brushing.
The lids are safe to sit on your dishwasher’s top rack.

A little over a year ago I purchased a 24oz. Iron Flask bottle for the gym and golf. After having the bottle for a year I started to notice rust spots forming on the inside of the bottom of the bottle. I then cleaned the bottle several times (per instructions), but the rust came back each time. After trying this process several times I contacted the seller and advised them of the problem. Per their warranty on Amazon “100% SATISFACTION GUARANTEED: We guarantee that the high quality Iron Flask bottle will surely please you! If, for any reason, you are not 100% satisfied with the Iron Flask, we will issue you a full refund or an exchange”. I advised their representative of the problem and how the bottle had been cared for. I also advised them that there is no damage to the bottle in any way, but it contuse to rust on the inside. I asked for a replacement since the bottle is obviously defective. After several emails, and me pointing out their warranty, they refused to replace it and told me it was normal wear (after one year). If they are going to state the above warranty and the bottle is used as directed, it should not rust on the inside when you are drinking from it. False advertising and very poor customer service!
Hi John. Thanks for contributing. I’ve been using the Iron Flask on and off for over a year–both for drinking in the field and for keeping sauces warm:) I’ve not experienced any rust. I think I’ve done a decent job of drying it after use but, regardless, it sounds like you deserve a replacement. Did you send images to them?
