  • Nice bottle. They really missed an opportunity with the logo though.
Size: 32 Oz Color: Aurora
I got the dark purple option of this bottle and it is super pretty and very handy. All the lids are leak proof and seem to be holding up well. I haven't put it in the dishwasher but it's easy enough to wash by hand. Keeps my drinks cold all day. Overall it was a good buy. My issue is with the company logo. The company (or bottle or whatever) is called "Iron Flask", and the little logo thing is an "F" in a square with a little degree dot up in the corner. Like fahrenheit inside a square. Like its cool if you want your logo to be something referring to temperature because this thing keeps your drink cold, I guesssssss it makes sense, but with some tweaking they could've made their logo way better. It could be an "Fe" with a square around it. So simple. So similar. Why would they do that, you ask? Because they're called iron flask, and "Fe" is the symbol for iron on the periodic table. This missed opportunity almost ruined the whole bottle for me because I literally can't even look at it without wondering why they wouldn't make that change. If they had a totally different logo, I wouldn't even give it a second thought, but it already looks soooooo similar to the periodic table symbol for iron, it's like they did it on purpose. Like there was some kind of meeting where all the little execs got together to figure out a logo, and someone said "listen guys, we can have a cool periodic table logo playing off the fact that our company is called iron flask. heres my sketch for the logo design, its just a square with Fe in the middle." and some dude named Chad was all like "Okay Bob you freaking nerd, no one knows what the periodic table is anyway. So let's take your idea and tweak it so it makes absolutely no sense. Who's with me?!" and everyone was with him, because Chad is cool and reminiscent of the high school jock they all wanted to be friends with, and Bob has unresolved high school trauma that was triggered by Chad calling him nerdy, so he won't stand up for himself and his awesome idea. And now we all have to suffer for it. I'm sorry for pointing this out to everyone reading my review. But if I can't unsee this missed opportunity, neither can anyone else. My hope is that with enough people taking the same issue with the logo, this company will finally cave and go with Bobs idea and tell Chad to shove it. I'd like a replacement bottle as soon as they do because it's inconvenient to not get the outside of my bottle wet so I don't ruin the sticker covering up the faulty logo. ... show more

  • Perfect size for a can of soda
Size: 12 Oz Color: Terrazzo
I love this little size. Perfect for a can of soda or just want to carry a little bit of water with you. The best part is the lid with the straw. When you have the mouthpiece down, it doesn’t leak! It comes with 2 other lids, (3 in total) so whatever your preference they have you covered without being charged. The most amazing thing, I can leave this in my car, in my drink holder, in the middle of summer (100 deg outside so 150 deg inside car 😉) sitting in the sun. I get into car and take a drink and it’s still cold!!! Both this size and the larger size bottles. I have other brands that do not retain the chill even tho they say they do. I now have a couple and will be getting another for my husband Ps. Love the colors too! ... show more

  • Great bottle - desert tested and approved
I live in the Mojave desert in CA, and I generally keep a water bottle in my car at all times. This one has traveled the desert with me, and the contents stay cold while I am grocery shopping and running errands. I had another bottle from another company that I had been using for these trips, but while it kept the contents cold, it didn't fit as well into the cup holders in my car. The 24 oz bottle fits perfectly into the cup holder and is a good size for my hand (my 32oz bottle is much fatter and so not as comfortable to carry). ... show more

  • Keeps my water cold and ready to drink.
Size: 24 Oz Color: Ocean
Overall, I love my 24oz Iron Flask. It keeps my water cold and easy to take on the go. It fits my hand comfortably. I went with the 24 oz size since the insulated cup I replaced with this bottle, didn't seem to hold enough when I'm on the go and was not conducive to carrying for outdoor adventures. My only disappointment (and the reason for one less star) is that the outer finish on the bottle has not held up. It has scratched off rather easily. You can see in the picture, that it looks beaten up. Ive had it a couple months. Several of my kids also own 20oz models of the iron flask and really like them (theirs still look great) which influenced my decision to purchase this brand. While I do take this bottle with me everywhere...running errands, biking, hiking, working in the yard...I wouldn't say I'm especially rough with it, so its appearance is disappointing however it does not impact its function. It is also a little difficult to fill the bottle from a refrigerator dispenser due to the narrow mouth. I use the straw lid (but love that Iron Flask provides multiple lids for different options) and like that I can close the spout and carry this where ever I go and it doesn't spill. I would definitely purchase Iron Flask again but would likely opt for the wider mouth bottle next time. Also, I purchased the carrying strap shown in the photo for easier carrying on outdoor adventures (it did not come with that). ... show more

  • All around great water bottle
I bought this for my 10 yr old son to use as his school water bottle. The kids all have to take their own water bottles to school. He loves it! It keeps his water cold throughout the day, and is the perfect size for him. We love the variety of lids that come with it! It's great to be able to change lid types depending on your needs. It seems like a very sturdy, well made bottle. Two thumbs up. ... show more

  • Keeps water cold but ice melts fast
Size: 20 Oz Color: Fire Red
All in all I really like this water bottle. It has a sleek design and it’s the perfect size for me. I love the straw too it fits comfortably. The only issue I have is when I put ice in it before I go to bed to wake up to ice water, the ice melts by the time I wake up for work in the morning. The good thing though is the water is still cold even when it’s been in my work van all day. Also, I’m not sure if it’s just the stickers I put on there or not but they don’t like to stay on very well. Overall this is a really good product and I’d buy it again if I ever need. ... show more

  • Multiple lids won me over!
Size: 24 Oz Color: Day & Night
To me, the thermos is like any other high-end thermos. The thing that won me over is the multiple lids! I can choose between sipping and gulping! I love it! They feel great in the had too. I bought the 24oz so it would fit in my car cupholder. I really appreciate that the company included a graphic describing that very thing before I purchased. Way to go on that! ... show more
