  • Perfect cup. Ladies, buy this for your man like my wife did. He will appreciate it.
Style: 40 Oz Color: Cobalt Blue
This is not a over priced cup that starts with an S, it is just a great cup made to keep your drinks cold and ice in your cup through a long hot day. I have put ice and water in mine and left it in the car accidentally on a day that got up above 105 degrees Fahrenheit, eight hours later the water was ice cold and refreshing as I drove home. The quality is amazing with the lid fitting tight and being very well insulated into the stainless steel interior of the cup which makes it easy to clean. Every bit of this cup speaks to care in design, thought for the customer, and attention to the purpose and functionality of what a cup should be. ... show more

  • Keeps liquid cold, even in extreme heat!
Style: 50 Oz Color: Cobalt Blue
I’m a team roping secretary and my office is HOT, like 7th ring of hell hot. I needed a bigger water jug that would keep ice and water cold in what I consider extreme conditions. Shockingly, this bad boy does it. The first time I used it, it was 95° in the office and 5 hours later, I still had most of the ice I’d started with, even after refilling the water twice. The amazing thing is I left it sit for a day after that and when I went to empty it out, it still had ice in it! Never thought I’d find anything better than a Yeti but here we are. I’m definitely switching to Iron Flask from here on out. Worth every. single. penny. ... show more

  • Great cup! Holds ice well!
Style: 40 Oz Color: Aurora
I love, love this cup. My husband gifted it to me on Mother's Day and it has been highly used. I'm a teacher so long days with no access to ice is my work day. If I fill it up with ice in the morning and refill it with water all day it will still have ice in it when I go home. I took it camping in Florida in 90 F degree weather and it held ice for 24 hrs! That alone made it worth every penny. I've dropped it, knocked it over, knocked it off tables and nothing spilled! The screw on lid held! The little flaps around the straw mean business. Nothing leaks around the straw. I haven't tipped it completely upside down, but I would expect it to leak from the straw then because there's no valve. At work I get so many compliments on the color and it is very pretty. It will show fingerprints, but those wipe off fairly easily. Even with me being clumsy the color still looks new and hasn't changed or chipped after washing. It's a large cup, but it fits in my car cup holder and the side pocket on my work bag. It's currently my favorite cup! ... show more

  • Fantastic ice retention
Style: 40 Oz Color: Aurora
We love these mugs! We took them on a long road trip through Utah and they were perfect. They kept ice in them for two days straight, sometimes more, even with the heat. It was amazing. They're easy to use, easy to clean and they're beautiful. They're made of quality material and we didn't worry that they would break in any way. Sometimes the lid would be on too tight and it was hard to get off but we might've tightened it too much to begin with. We've only used the lid with the straw and it's very easy to drink out of. We're very happy we got these! ... show more

  • Great cup, needs better lids
Style: 50 Oz Color: Cobalt Blue
Bought it to replace a similar cup that leaked and almost caused a fire when it dripped on my phone/charger. My 2nd one from Walmart had zero insulation. I left it somewhere and didn't even care to look for it. As for this one, I LOVE the cobalt blue color, and it's got great insulation. My only complaint is about the lids. The flip-top screws on so that the mouthpiece is in the most awkward place and won't change no matter how you try to screw it down. It's pretty much useless. I went with the 2nd lid where the straw is in the middle so it doesn't matter how you screw it down, but I hate having to crane my neck and tilt it more to reach the straw, which causes it to leak on my chest when it's full. Other than the lid issues, it's great, and so far, it's the winner in the 64 oz class. I have other Iron Flasks and they are all great too. ... show more

  • Better Than A Stanley Cup
Style: 50 Oz Color: Aurora
I absolutely love this thing. I wish I would've bought one sooner. It's perfect for someone who lives in the desert. I drink it and fill it up again to make sure I'm drinking enough water during the day. It's better than a Stanley cup and not as expensive. The colors of the cup are beautiful and the lid stays on tight. It stays cold for several hours and it is perfect for work. It is also easy to clean. Buy one, you won't regret it. ... show more

  • Fave Tumbler
Style: 40 Oz Color: Cashmere Cream
Why did you pick this product vs others?: LOVE this cup. I spent too much time researching because I wanted a 40oz cup but did not like the giant look of the popular brands. I compared measurements and read plenty of reviews and finally decided on this one and I’m so glad I did. I love the two lid options and extra straw. I loved it enough to order one to replace my husband’s tattered cup as well. This cup holds ice, my friend has already knocked it off a table while camping and it survived the fall flawlessly, it fits in all my cup holders. ... show more

  • My favorite cup
Style: 40 Oz Color: Dark Night
I've been using this cup for 7 months and I love it, but would be 5 stars if it came with a cleaning brush for the straws. I've switched to using the second top with the slide because I cannot get the straws clean fully and I haven't purchased a brush long enough to clean them yet. As for what was included: I love both tops (the straw one being my favorite). The cups keeps my beverages cool for a few hours but not all day because I don't use ice. I'm in love with the ombre colors and I don't mind the weight of the cup when full because my beverages last a while! I don't leave home without it often, if I do it's because I forgot it! Will be looking at other items from this brand. Thank you all! ... show more
