Excellent flask, very convenient!
Excellent product! I work from home and picked this one for its size and the fact I have another bigger flask that has served me good. Also, when I am in meetings, I prefer to use the straw which makes drinking more discreet (just my personal thought). I compare it to my daughter's Stanley thermos and find it much better, less bulkier and the straw is more compact and it will not allow the 85+ degrees temperature I am around most of the time to warm my drinks even if I leave it upright for long time. It keeps my drink cold during the day until I finish it, and you can still hear what's left of the ice cubes when you shake it after done. Not sure if it is because it's new and I've been using it for a few days now, that I have to suck a little stronger, but you get used to it easily. The outside looks nice to me and it is perfect to fit in my car's cup holder too. An important thing for my desk: It never sweats, and when accidentally hit, it has never leaked over my papers, nor had a scratch... phew! Cleaning is easy with a brush, like with any other tall glass or container.

Top notch adult water bottle, keeps cold, really cold!
I am so delighted to post this review because I am happy to have tried out this brand. I purchased this for my 10 year old boy and got myself a big bottle of 32 oz and I love everything about it. I liked the options it came with. The color I selected is beautiful like a purple with green reflection background really cool and chic. I like how sturdy, durable and the colors. They really offer all different sizes with is great and convenient. Not to mention, this brand really works great for keeping my water cold!!! I haven’t tried hot liquid but for cold works wonders! So happy and I am definitely an ongoing customer. You will not be disappointed.

Ideal drinking flask
My first use was coffee. I traveled that day and the Flask kept the coffee warm all day. I then used ice mixed with water and the flask did fantastic. The flask comes three different lids. One with a straw for sipping another for straight drinking. A third lid for pouring .

Great flask!
Used these hydration flasks for years. Love them. Water stays cold hiking for an entire day. Colors are beautiful. Love that they come with multiple types of lids. I’m a flip top person.

Great buy for a kid who loses water bottles often!
I have a teenager so I’ve purchased this same water bottle several times. The quality is great and it’s more affordable than other brands. I like that it has different lid options. It seems like it would last a long time but I don’t have a ton to say about that because my kid loses them way before they wear out. He likes to use a caribiner clip to attach it to his backpack so I will say none of the lids have broken while clipped on to his bag. It’s a good size for school and holds plenty of water. I would recommend this water bottle, especially if you find yourself buying water bottles pretty often.

Durable and Well-Insulated Bottle, but Lid Quality Could Be Better
Product: IRON FLASK 22 oz Water Bottle Used for: 2 years and 6 months Key Features: – Excellent insulation for keeping drinks cold – Durable stainless steel construction – Comes with multiple lid options – Stylish design (I got the “Dark Night” color) Ratings: Quality: The bottle itself is rock solid—durable stainless steel with a finish that’s held up well over time. The weak point is the lids. They feel cheaper than the bottle, and the mouthpiece lid I used the most actually broke, which was frustrating. Rating: 4/5 Performance: It performs really well. Drinks stay cold for hours, cleaning is simple, and there’s no weird metallic taste. I only use it for cold drinks, so I can’t speak to hot insulation, but for my use it’s been great. Rating: 5/5 Value: It’s a little on the pricier side, but considering the durability and insulation quality, I’d say the value is still there. Just wish the lids matched the quality of the bottle. Rating: 4/5 Pros: – Excellent cold insulation – Durable stainless steel build – Sleek design with nice color options Cons: – Lids feel cheap compared to the bottle – Mouthpiece lid broke after extended use Summary: The IRON FLASK 22 oz Water Bottle is a tough, stylish, and well-insulated bottle that’s kept my drinks cold for over two years without issue. The biggest drawback is the lid quality—mine broke, which is disappointing given that it’s the part I used the most. Still, the bottle itself is excellent, and if replacement lids were better, it’d be close to perfect. Overall Rating: 4/5 Disclaimer: This review is based on my personal experience using the product. I’m not an expert—just sharing my honest thoughts to help others make an informed decision.

Great Flask for everyday use
Great quality, comes with 2 straws for the straw top, and keeps cold things cold and my coffee hot for long periods of time. 32 oz is a great size, highly recommend. its very tactile so its easy to hold while cold or warm.

I have bought 2 bottles and I am very happy with this both of them. Even though it is 32oz it is lighter than my other smaller bottles and not so big, easy to hold. I mostly use cap with the straw and it works great. 32oz It does not fit in the car cup holder. 22oz does fit in the holder. Both hold cold water even the next day

Very nice water bottle, fit just right on my bicycle adjustable bottle cage, it came with 3 lids, a big plus as the two spare lids fit perfectly on my others Nalgene water bottles. recommended for sure.
