Customer Reviews
Got a new bottle, it's pretty good
So, I needed a new water bottle and heard good things about these. Grabbed a 18 oz Kids Water Bottle for my son, since he kept losing his others. It came pretty fast, like four days, and the color is nice. He dropped it already, of course, but it seems to be holding up. No complaints from him, and his water is still cold when he comes home from school. All in all, a good buy.
Decent value, small issue
I picked up a 22 oz Narrow Mouth Water Bottle during a seasonal promotion. The price was good, and it feels sturdy. It keeps my coffee hot for hours, which is what I needed. Delivery took about 5 days to reach Denver, which was reasonable. My only minor gripe is the color wasn't quite as vibrant as it looked online, a small detail, but noticeable. Overall, a solid purchase for the price.
Got a good deal on a tumbler
I was looking for a new insulated cup and found Iron Flask had a clearance sale. Picked up a Retro Tumbler, 24 oz, for a good price. It felt like a solid deal, especially compared to some other brands I looked at. Shipping was free because I spent over $35. It feels really well made, and I'm happy with what I paid for it. Definitely worth the purchase.
Always reliable, great bottles
I've bought several bottles from Iron Flask over the past couple of years, and they've consistently delivered. This time, I got another 40 oz Wide Mouth with the straw lid. Just like my previous orders, it shipped fast and arrived in perfect condition. The quality is still top-notch; it keeps drinks cold all day. It's why I keep coming back.
Obsessed with my new flask!
I just got the 40 oz Ombre Finish Water Bottle and I am absolutely in love with it! The color is even better in person. My drinks stay ice cold all day long, it's seriously amazing. I've been showing it off to everyone! This is my new favorite bottle, and I'm already planning my next order. You have to try these!

Does Iron Flask do any kind of student discount? Trying to save a few bucks.

I'm thinking about getting an Iron Flask but also looking at Hydro Flask. Is there a big difference in quality or performance?
