    • Great Vessel
Style: 40 Oz Color: Black Speckle
I recently bought a nice water filtration system which has allowed me to completely ditch plastic water bottles. I wanted a replacement for my normal 1L glass mug and found the 40oz Iron Flask. True to its description, this insulated mug does a great job at keeping cold liquids cold. I haven't tried with hot. If I pour refrigerator-cold water into this mug in the morning, it will still be at the low end of cold into cool in the evening. I can imagine even if I had the same water in their for an entire day, it would still be cool. I prefer my water ice cold, so this mug works perfectly for me since the water never lasts long. The mug comes with 2 lids. One has a hatch lid for sipping, and the other a simple hole for a straw (2 straws are included). My wife has gone through +10 water bottles over the years and she ditched her newest fave for this one after seeing how simple the lids are for cleaning and use. Another great aspect of this mug is the weight. Even completely full, this mug is very well balanced and easy to carry for both my wife and I. These mugs look cool too. I chose the black with white speckled and my wife chose the blue/dark blue gradient. Both have a great look and feel. The coating isn't rough at all. I would feel zero shame in bringing one of these around while running errands. Overall this mug exceeded our expectations and is highly recommended! ... show more

    • Great Quality
Style: 40 Oz Color: Aurora
Love the color! I own this in several sizes and feel the quality is excellent. This keeps things cold for over 24 hours - it's amazing. I gets compliments on it all the time. I love that it comes with two different lids for versatility. I typically use the lid for the straw and find it barely leaks if tipped over. I carry this with me everywhere I go. ... show more

    • LOVE
Style: 32 Oz Color: Aurora
My new favorite cups...I bought two of them. The purple/blue gradation color is gorgeous! Great size, fits in my car cup holder and holds a generous amount of liquid. Keeps ice and drinks cold for over a full day (one time I filled it up with ice and water in the early am, then came home and put it down and left it there overnight and didn't open it up again until the following evening, and there was still ice!). I appreciate the rubber bottom, which keeps it from sliding around or making noise when I put it down. I like the two lid options, both have good functionality. The straw lid seals around the straw quite well. The handle is very convenient. I only wish the company sold replacement lids and straws separately. ... show more

    • Amazing cups and fantastic customer service
Style: 40 Oz with Boot Color: Azure Mist
Review Image by Kristie
I love Iron Flask Copilot cups! I like them even better than my expensive Stanley cups, and I find the Iron Flask cups keep my cold drinks cold longer than my Stanley. I can put ice in it in the morning and the ice is still there all day. The price is great and the quality is spot on. I’m a vet tech and I call my cup my “emotional support cup.” Even other techs I work with have bought them. Their color options are great as well! Their customer service is amazing as well. The cup I just purchased had an issue with one of the lids. I contacted them and they quickly responded to address the issue. Out of all of the Iron Flask cups I have, this cup was the only one I’ve had any issues with and they quickly helped me out with it. Highly recommended! ... show more

    • Good for its price
Style: 32 Oz Color: Cashmere Cream
Had it for a week or two. Not bad for the price. Hand wash only but just a simple dish soap rince is enough to clean it. Lid quality is okay, so far it doesn’t leak we will see in the future. It keeps the drink cold or hot for a long time, like overnight long time. It is sturdy but doesn’t balance itself too well and falls on its side quite a bit. Good thing it doesn’t leak so far lol ... show more

    • Hitting my water goals finally
Style: 32 Oz Color: Aurora
I’ve had for a week and my water intake has already tripled. Who knew all I needed was a cute bottle to take everywhere. I’ve only had washed but the parts are easy to disassemble and reassemble. It takes some elbow grease to put back which I like , I want it to be as leak resistant as possible. I get compliments all the time. I’m a hot water drinker and it definitely keeps the liquids hot for hours. Not that they normally last that long. Love that it has different lids and I use both interchangeably although the straw lid gets the most use. Great price since other brands easily charge double. Will probably get another for work so I don’t have to take this one with me. Absolutely adore that it fits in the cup holder of my 2018 Buick. ... show more

    • Great for the gym
Style: 40 Oz Color: Burgundy
This tumbler is GREAT with the screw on lid. If it spills over very little comes out so an easy cleanup if that happens. It keeps my hot tea hot and my cold drinks cool. No funny metal taste. Get a straw brush cleaner to keep it fresh. Fits well in my vehicles cup holder. I have the 40 oz and it holds 4 cups liquid plus ice. I had to throw out my last tumbler because it had the type of lid that just pushed on - no screw down. It was a disaster in the gym and the second time it spewed protein shake on the gym floor I promptly threw it in the trash. ... show more
