I am so impressed with my Iron Flask tumbler! It keeps my water ice cold all day long, even when I leave it in a hot car. The double-wall insulation really works. I also use it for coffee, and it stays hot for hours without any weird taste or leaks. The quality feels really solid, and I love the sleek design. It fits perfectly in my car cup holder and is easy to clean. I’ve tried other tumblers, but this one is by far my favorite. Highly recommend if you’re looking for a reliable, stylish tumbler!

Serious fan of quality tumblers. I have several Iron Flasks in various colors and sizes. This rose gold color is pretty. More importantly, this is a quality brand to purchase because it keeps beverages properly cold or hot. As a teacher, I don’t have time to be rummaging through my lunch bag for drinks. I just pour my tea or whatever I’m drinking that day in my tumblers right before I leave for work at 6:15am, and they keep cold through the end of the school day at 4:15pm.

I'll say this again, I hardly ever leave reviews on anything. The Iron Flask very much deserves one! I use this mainly as a water bottle for my work day and it's probably the best one I've ever used. The overall construction feels very premium and solid. It has a nice grip to it, and the lid seals completely with no leaks or air coming through. Cold drinks stay cold and hot drinks stay hot for a *very* long time. I've also gotten many compliments on the way it looks. One other surprise for me was the soft bottom. This makes sure it doesn't make a loud noise when you place it onto a table. Just a 5 star product all across the board!

OMG! I will never but another brand. This is affordable and it keeps the ice for so so so long! Even when its 100 degrees. I am in love with my cup. II do suggest getting a cool straw to go with it thought, comes with 2 plastic ones that are durable. So COOL though. Literally.

If the actual amount of what you are drinking is important (for example I've been told to drink so much water a day) this is not a good measuring device. It is not 24oz. At best it's maybe 18oz - a 16.9 basic water bottle almost fills this cup. It is spill resistant not spill proof. It keeps things cold for long periods of time. Love the feel and size of it. Be extra careful to clean the lid - specifically the spot around the straw hole on the underside - take a q-tip to it to really get the liquid out otherwise it will grow stuff. Love the fact that it comes with different lids, easy to clean, transport. Would recommend but watch out for those lying ounces.

I have had this cup around 24 hours. I put ice water in it around 10 PM. It is now 5 PM of the next day, and the water inside my cup is still suitably cold! This is the best water cup I have ever had. Plus I like the size and color.

The media could not be loaded. I have been looking for a 100% LEAD FREE tumbler (verified by customer support) for a very long time. This is perfect! These things range from 14oz. to 60oz. and come in a dizzying array of stunning colors from boring to cute. I am so happy I have finally found my last tumbler. Here's to a lifetime of sustainable hydration! “Hello there, Thank you for purchasing our product! I'm happy to share with you that our bottles are 100% lead-free. There is no lead that would reach liquids by any means. We do not use any leaded materials in the process of making our water bottles. All materials used are food-grade, safe, and FDA-approved. In addition, our bottles are double-layered and vacuum insulated which means no material outside could reach or affect the interior of the bottle. No lead is also used in the construction of the Iron Flask water bottles but rather "Heat welding". Our flasks are not soldered; instead, they are molded with stainless steel and painted with lead-free paint. This includes the bottom center part of the bottles. If you would also like to know if the paint is lead-free, it is!” UPDATE: Nearly perfect. I'm not taking a star, but there is one issue with this tumbler. If you are exact with your water intake like I am and keep track of your water intake daily, I have an important detail to share with you: While this tumbler is technically capable of holding “32oz” (≈946 millilitres), you have to fill it up over the threads of the tumbler, nearly to the top of brim of the tumbler, and doing so will not allow you to put one of the lids it comes with on it. This isn't a big deal for me around the home because I don't use the lids there anyway. I use this as a giant stainless steel cup and have a pretty pink flower Daiso melamine coaster that lays perfectly on the top of this to protect the lip and contents. Somehow it has a perfectly 3D printed inset of a few millimeters that fits into the tumbler exactly so that it can't slide around or off the top of the tumbler when I'm walking around with it and jostling it throughout my day. This serves the purpose of a very low profile, slim lid that keeps dust out while not in use. But if I go out on a hike and buy two bottles of water to consolidate into it as intended, they're not going to fit and will overflow when I try to screw a lid on. Filling this up to the threads only gives you 839ml of water as opposed to a full 946ml. So you'll have to chug that remaining 107 before trying to use one of the lids it came with. Again, it not being an exact 946ml/32oz. with a lid probably won't be an issue to most people, but I purchased this for hydration tracking and so I could know that I just need to drink 3 of these in one day and I'm done with my water intake. I really didn't want to worry about drinking three of these and then breaking out the scale to measure the remaining change of 321ml that adds up to I need to hit my hydration goal for the day. Again. Not too much of an issue because I can just fill this up and drink to the threads if I need to take it out of the house with a lid, but just be aware, if you are just filling this to the threads, you are not drinking “32oz.” a tumbler and this will add up to missing out on 321ml of missing hydration a day. So just a heads up, if you think you can put 32oz. into this and use the lids, you can't. So just fill it to the brim and drink enough out to use a lid if you need exactly 32oz. of water.

Ok I want to make this review short and to the point. I have tried Meoki, Brumate , and Iron Flask. I didn’t realize how hard it would be to find an insulated travel mug that actually keeps my coffee hot for more than 30 minutes. I have the iron flask 16oz and it actually keeps my coffee hot for more than 4 hours! I wanted something a little bigger and I thought paying more money for an insulated travel mug would mean they also kept my coffee hot…Wrong! So I went back to Iron Flask and found this 24oz one and it was on sale for $15!!! I was over the moon happy and bought it immediately. The only thing I don’t like about it is it has no handle like the 16oz one but I bought a handle I can add to it so I can carry it in the mornings with all my stuff and to my delight, my coffee stays hot again! Now the 40oz is on sale and I will get that one for my water and ice. Thank you Iron Flask for making a product that is cost effective and actually does what it says it does! Pictured is my 16oz that I beat to heck with all the uses and my 24 oz new one. I wish I would have registered my 16oz to replace it because the design on the handle has worn off but it doesn’t affect the performance of this fantastic insulated mug! I highly recommend this product! Ok I guess my review wasn’t so short.
