    • 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

    • The trusty water bottle
Size: 32 Oz Color: Dark Night
I was looking for water bottle that absolutely did not leak AND had a straw! I throw this into my bag all the time, and it does not leak. ever. I would recommend this bottle to everyone. The other tops are also really fantastic and easy to use. I just drink more with a straw, so I predominantly use that piece. Importantly - you need to make sure to close the top all the way. If it is open/up, it will leak a little bit. Of note - I drop everything that I own, multiple times a day. So this water bottle probably hits the ground at least 3x a day. It has sustained some bruises, but nothing major. The little plastic piece that sticks out on top of the straw did break off, but that was probably after I dropped it for the 200th time so that is on me. ... 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

    • Love the narrow mouth straw.
Size: 24 Oz Color: Fire
I bought this to replace my Thermoflask wide mouth straw which didn’t work well since they changed the model from a soft straw to a hard straw. I love this Iron Flask model as the bottle is 24 oz and narrow so it fits in my car cup holder even with added boot which I added to it. I learned a while ago that if you going to own a stainless steel water bottle that it needs to have a boot so it gets protected from dings and is less noisy when put down. The bottle is easy to hold as it is narrower than my previous water bottles. It is easy to clean. I love the narrow straw since it is easy to sip. I drink a lot of water so this bottle suits me very well. ... show more

    • Wow!
Size: 24 Oz Color: Lime
I just bought one of these for work as I wanted something that was going to keep my water cold all day long. Well, this 24 oz. Iron Flask water bottle is living up to all of these rad reviews. My ice from the morning is still in solid pieces in the late evening. I mean, I couldn’t ask for more except that they provide the more by having 3 different lids and 2 straws. The price point is great too. Go ahead and buy two, because I am now going to buy a smaller one for my coffee. ☕️ ... show more

    • LOVE MY WATER BOTTLE
Size: 32 Oz Color: Bubble Gum
I have been using this water bottle since 2020, and I take it with me EVERYWHERE. It does really well with keeping my water COLD for long periods of time. Also, great customer service. I accidently broke my lid, and they replaced it with three new ones. 10/10 would recommend 👌

    • Good bottle.
Size: 20 Oz Color: Midnight Black
Bottle does the job. I like how it comes with 3 lids, but I wish they were a little more solid... The plastic lids feels like they may fail after a long time of use. We'll see!

    • Great water bottle
Size: 24 Oz Color: Twilight Blue
I'm very satisfied with this water bottle. I previously had a plastic bottle with a flexible straw and mold/mildew was an issue. This bottle is very well made - metal but soft texture on the outside. The finish holds up very well and has withstood several bangs and bumps. It comes with three different caps, including a fixed cap, a flip cap, and a straw cap. It keeps water nice and cold for hours and there is no metallic taste - the water tastes great! Further, the 24 ounce bottle fits automobile cup holders pefectly. ... show more
