- Reviewed in the United States on March 16, 2025Size: 64 OuncesColor: Dark NightVerified PurchaseThis is a great flask that’s very durable and flexible.
This is my second flask from this same company and I’m always impressed by the quality. My original 1 gallon flask lasted me for years and was very solid. I went with this smaller flask because it’s much easier to carry around while still holding a good amount of water. During the summer in the peak heat it always keeps the water crystal cold and it helps tremendously for my outdoor job. I’ve always loved the colors and designs and the three interchangeable lids are a game changer for me.
- Reviewed in the United States on March 18, 2025Size: 18 OuncesColor: SageVerified PurchaseI have had the bottle for only about three days but so far I am very pleased. I like the fact that it holds a full 16.9 oz water bottle and holds the cold temperature for quite a long time without ice. I do like the assortment of lids that are supplied. I prefer the straw for cold drinks and the flip up spout lid for hot drinks. the build quality seems to be very solid. I also liked the wide variety of color options. The handle makes it easy to carry and has a small carabiner of sorts on one end that I have not tried yet but looks solid enough to hook on a backpack, belt loop or whatever. I like that fact that it fits nicely into the cup holders on my vehicles. The price point is very reasonable for this build quality but time will tell on that point. I would definitely recommend this bottle and will most likely purchase another one.
- Reviewed in the United States on March 13, 2025This thing is just fantastic. It's very reasonable in price, not bulky, and has an attractive design. I love that it keeps water super cold--even during a sauna session! It keeps ice frozen overnight as well. It is a good value for the money and I highly recommend it.
- Reviewed in the United States on April 4, 2025Size: 40 OuncesColor: Lavender BlissVerified PurchaseI love these bottles! This is my second one. They're pretty much indestructible and have a perfect surface for stickers. They keep water cold forever, keep ice frozen over night. The design makes it easy to get a big drink of water to take meds, it's easy to open but stays closed. I love the color options, too!
- Reviewed in the United States on March 14, 2025Size: 40 OuncesColor: Rustic BerryVerified PurchaseIt's a good size and is convenient. It has a clip that I use constantly to attach to my bag.
It has 3 different lid options.
I can drink warm/hot water with it and it keeps the temperature the same for HOURS.
The color is lovely as well.
- Reviewed in the United States on March 19, 2025Size: 40 OuncesColor: Dark RainbowVerified PurchaseThis is a great water bottle with one downside.
The 40oz bottle does NOT fit into a standard vehicle cupholder. I have not found one vehicle with a cupholder to fit this (even a minivan), which is honestly a pain. Top occasionally leaks, so I have to be careful where I keep it in the car so it doesn't fall over and drip everywhere.
For positives, I love the color, the different tops that come with the bottle, and it truly does keep my water COLD all day. I prefer the pop top; it is quick to open and easy to clean.
Rating the 40oz 4 stars due to leaky cap and incompatibility with standard cup holder. Would rate 4.5 if I could. Overall, would buy again but in a smaller size.
- Reviewed in the United States on February 13, 2025Size: 64 OuncesColor: AuroraVerified PurchaseThis is my second Iron Flask and I love it! They are such great quality and keep your drink cold all day. Way cheaper than other brands too. I use this at work, at, home, on the go, for everything! I have to watch my water intake and this big one help tremendously. I love this brand and have so many of they bottles!
