    • OBSESSED with my Iron Flask!!!
Size: 24 Oz Color: Peach
I was desperately in need of an everyday, go-to water bottle that I could take with me as a busy, working single mother - so I could keep up with my water intake, and I am BEYOND happy with my purchase of this Iron Flask! I had been shopping around, looking at all the top contenders, but had been on the fence. I found many competitive options to be overpriced simply due to popularity and hype, so when I found the Iron Flask and I felt it offered great value at its price point. Plus, it came with all 3 different lids - straw, gulp, and screw on - and this had been another point of contention for me, because I wasn't sure which lid I would prefer, and competitive options only offer one or the other, generally. I love the flexibility that having all the different lids offers. Also, the Iron Flask comes in lots of beautiful colors, AND they offer options that are easy to hold and fit comfortably in a cup holder and bag. I've taken my Iron Flask with me everywhere since the day I received it - it doesn't leak or sweat at all, and it keeps my water perfectly cold! I throw it in my bag, take it with me on bicycle rides, keep it at my desk, in my car, take it to the gym - just everywhere I go! Highly highly recommend as the best water bottle on the market today. It really checks ALL the boxes!!! ... show more

    • 3 lids!!!!!
Size: 32 Oz Color: Cotton Candy
Ok, so 1) the colors look just like the photos. 2) it's kept my water cold all day, and ice is still in it!!! (I can't stand warm water so this is a big deal) 3) it comes with 3 lids! I'm so happy. One for keeping it 100% closed, like maybe If you're on a bike. One that's like a sippy lid like coffee cups, where you slide it up to drink and one with a straw that pops up! I love it and I'm so happy. Really I wish I had more room and money for multiple colors! ... show more

    • Best water bottle I own
Size: 20 Oz Color: Day & Night
Review Image by Lisa W Lisa W
I love my iron flask. It keeps water cold allll day. It doesn’t leak. It’s BPA free. It comes with 3 different lids. This was key for me recently when I couldn’t use the straw lid (which I prefer) because of dental work, and remembered I could switch it out! I also recently had a piece of plastic break off one of the lids, but Iron Flask stands behind their product and I had a new lid in a few days. Will be buying a few more in different sizes and colors for myself, and as gifts. Highly recommend. ... show more

    • Easy on the arthritic hands to open

I got this to replace a slightly fatter bottle that I was struggling to open due to developing arthritis in my thumb joint. I love that this come with 3 lids, so I can switch out when needed. I prefer to have a straw when I take it in the car, but like the chug lid at home. The water stays cold, though I haven't tried it in the summer heat, I am expecting it to keep it chilled. The color is amazing and I am so glad I waited for it to come back in stock for the 24 ounce bottle. The color does not look exactly like the one shown, but I am happy with the color variations. It loses a star because I am worried about the handle part of the straw lid not holding up over time, since pressure gets put on it when trying to open the bottle, but otherwise I love it! ... show more

    • Great Product - I Own 3
Size: 24 Oz Color: Dark Rainbow
I love IronFlasks. This is the 3rd IF I have purchased. I purchased this one to use at the gym because it fits into the bottle holder on the equipment. I love the patterns and colors available. I volunteer at a zoo and use a 44oz bottle that purchased for it's volume and coloration (it matches my uniform). I often spend hours standing in the sun on 90+ degree days and my bottle keeps the ice frozen and water cold. ... show more

    • If this was a contest, this flask would come in 1st place.
Size: 20 Oz Color: Rose
Review Image by ColaD. ColaD.
This flask is easy to grip with one hand. The look is sleek and the color is as described. The most important thing about the ironflask is that my liquids stay so cold. I think it's colder after it's been sitting for 8 hours, colder than when you poured it straight from the refrigerator. I love it. I will be purchasing a second one for my job. Trust me you will not be disappointed! ... show more

    • Soooo Worth The Buy!!
Size: 24 Oz Color: Bubble Gum
I have owned quite a few high quality Hot&Cold products in the last 10 yrs. This Beats them all. Have not used it for Hot temperatures yet. Ice literally stays in the bottle for over 24 hours. I work 9 hrs a day. At 7am I put ice filled to the top. I get home by 5pm, refill with lemon water, (twice before bed,three times during the day). In the morning there is still ICE!!! Not alot, small amount, but it is there. At that point, shake the bottle to loosen the ice to remove it. Also (⚠️) What ever liquid you put in this bottle, will be Extremely Cold!!!. Personally I love really cold liquid products. But this is Cold. Which means, if you're Exercising,running, DON'T Inhale long sips. Take slow sips. Still worth buying!!. ... show more

    • This thing holds up!
Size: 64 Oz Color: Fire
I do warehouse work and this thermos has flown off a pallet Jack going 20 miles an hour more times than I can count. It’s very easy to clean and the water stays as cold or warm as I need based on the area I’m working. The straw is a very nice feature you don’t see with other thermoses because you can use it anywhere without worrying about contaminants or stopping to unscrew the lid. Hands down the best thermos I’ve ever had. I’ve bought them as gifts for others but I’ve never had to replace my own. If you need to drink water, which most of us do, and you like having it with you, then look no further. ... show more
