Don't Let Anyone Steal Yours!
My daughter gave me one of these 40-oz Iron Flask bottles for my birthday in April. It comes with three different types of lids, for different situations or preferences, and it was just AWESOME. I babied it for a few weeks around the house and in my workshop. But on the third day that I took it to my day-job, someone stole it when I wasn't looking. I loved it so much that I just had to get a new one. There are a lot of color options to be attractive to pretty much anybody, but the durability and overall quality of this product is impressive. If you don't mind paying a few extra dollars for a higher quality product, this should be your go-to thermal bottle for work, recreation, sports, hiking, camping, fishing or even long drives. Now that I have this one, I want to get another one in a different color.Just don't let anyone steal yours, because people recognize quality when they see it.

Will Keep Beverages Cold!
I bought this bottle, trying to replace some Hydro Flask bottles that prematurely had the seal break. I had regular expectations for this bottle. I wasn't looking for anything more that to carry my water for the day at work. But this bottle set the bar high for any other bottle I may buy in the future - if it's not one like this one.It truly is insulated and keeps your beverages cold for a great deal of time.I filled the bottle up with ice and added water and went on a work trip. By the next morning, I went to fill the bottle up with water and was surprised to see that there was still half a bottle of ice left. By the following morning, I filled it with water again and it still had a quarter of the bottle with ice. This was during the summer and I never added ice in the entire time and it took 4 days to melt fully. I love this thing!

Love it
Keeps my water cold for several hours- not quite all day, but close enough. Color looks great in person. Big enough to hold all the water I need while out and about. Worth the money for sure.My only complaint is that I dropped this bottle once, just days after getting it. It had the added rubber grip at the bottom. The bottle dented and the paint scratched right off, even though it only fell from about 14" away from the ground. I haven't dropped it since because I bought a paracord handle for it, but for what I paid, I'm a bit upset that the bottle was so easily damaged.

Love this bottle!!
I left the house at 830am on my motorcycle with this water bottle mounted on the handle. It was full of water and some ice. The temperature was 92 with a heat index of 105. I rode for 3 hours, had lunch, rode 3 1/2 home and the water bottle stayed on the bike all day. The water was very cold all day and it still had ice in it when I got home. I love this water bottle. You will not be disappointed if you buy one of these. I have the 18oz.

High quality and functional
Love this bottle. Keeps ice pretty much all day and not much melting at all. Holds plenty of fluid and the straw drinking option is fantastic to use. The carabiner hanger is nice, and I also added a paracord hanging accessory to it, so it gives me options for carry or keeping in my vehicle when driving. I use this every day and works great and is very high quality. I looked at other brands and never had an Iron Flask brand but will certainly buy this brand again.

Great value for sturdy water bottle
Sturdy bottle keeps water cold for several hours, if you chill the bottle first. The flip top lid does leak if it tips

Love these! I'm definitely addicted!
I never understood the Stanley craze until I started buying these bottles. I bought my first in 2022, and now I have a full on collection of them! (And just bought another today LOL). In my defense, I take 2 with me to work daily, and sometimes need another 2 for the next shift if I'm working a double. (One is for a caffeinated cold beverage, the other is always for H2O... and I'm a snob and only drink filtered water from home with ice made from filtered water). Having more bottles means that I can go a few more days before washing all of the used ones!First the negatives: as pretty as the "aurora" color is, it is a different texture and scuffs/scratches very easily. I have not had this problem with any of the other colors (although the rose gold is a slightly different texture as well). I have broken one carabiner clip on a straw lid, but I tend to fidget with them when stressed/bored so not unexpected. The bottom of the bottles can be a little slippery depending on the surface - I bought 2 silicone boots to negate this.Now the positives: I like my fluids ice cold, and each of these bottles keeps my drink cold with ice frozen for about 36-48hrs depending on the outside temperature. I haven't tried them with anything hot at this point. They never spill, as long as I actually close the lid correctly (I only use the straw lids... not the other two that each bottle comes with). I like that the straw lid folds down, which is why I don't have more of the copilots. They are easy enough to clean with a bottle & straw brush. I do admittedly switch between them daily, but no signs of mold growth in any of them, ever. The bright beautiful colors make them stand out and prevent them from "walking away" with a coworker "accidentally". They do not make noise when drinking and the separately bought silicone boots keep them silent on the desk, but honestly are not necessary - I just prefer them. The brand also has a paracord handle that works fine, but I don't typically use the one I bought.For reference, the attached pic is a 22oz elemental grey, 32oz blue waves, 40oz dark night & bubble gum & aurora, and then 40oz copilot in rose gold. I included a pic of a scratch on the Aurora from one single trip inside my work bag. The others make the same trip daily (and have for 3 years now) without a single scuff.

Huge bottle that does the job
This bottle is great! It keeps things relatively insulated, and honestly is a good shape for its size. I mainly just wanted a large bottle that I could just fill once a day, and this did the job great. Super durable after many drops outdoors, no visible leaking and easy to carry if you get the paracord thingy too. Would recommend, especially if you get it for $20 like I did.
