    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.

    Sturdy, Cold All Day, and Looks Great
    I’m a longtime fan of Iron °Flask bottles—this 40 oz size is just the latest addition to my personal collection (yes, I rotate through several like they’re outfits). I’ve also bought dozens of these as gifts over the years, and they’re always a hit.Every single one I’ve owned still works perfectly, even the older ones. A few have some scrapes and bumps from being dropped (I’m clumsy—it happens), but they still keep my water ice cold all day and haven’t lost their seal or insulation.I love that it comes with three different lids so I can switch things up depending on whether I’m driving, walking, or just lounging. The quality is super consistent, and they’re easy to clean and carry.If you’re on the fence, just get it. I basically evangelize these to everyone I know and have yet to hear a single complaint.

    Nice and Cold! Love them!
    Bought the blue and white/black. Have had another bottle in the past for my children that we brought to Disney and loved that the ice and water temperature lasted all day/night in the parks and stayed nice and cold. Love the colors! Love that it fits into their backpacks or cup holders in the car. And it doesn’t leak so it’s great for school.

    Got to Buy This
    This is the best water bottle! Price is reasonable. Easy to clean. Drinks stay cold even on the hottest of days. Bought this for someone because they liked mine (different color). I love Iron Flask products!

    Love it – 22 ounces Cashmere Cream bottle
    I got 22 Ounces Cashmere Cream bottle , perfect size and color for me ! Hold cold all day , didn’t try the hot beverages in this one yet , but i did have different iron flasks tumblers before and i know it hold cold and hot temperatures for a long time . Got this one mostly for sport and easy access of water due to the caps , but i love the choice of 3 different ones , very versatile. In general always had a great experience with this company, hooked my friends on them too , everyone loves the quality! Very much recommend this bottle , 22 ounces is great size for running everyday errands or sports .

    Durable and Well-Insulated Bottle, but Lid Quality Could Be Better
    Product: IRON FLASK 22 oz Water BottleUsed for: 2 years and 6 monthsKey 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: 4/5Performance: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: 5/5Value: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: 4/5Pros:– Excellent cold insulation– Durable stainless steel build– Sleek design with nice color optionsCons:– Lids feel cheap compared to the bottle– Mouthpiece lid broke after extended useSummary: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: 4/5Disclaimer: 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.

    Absolute must have
    This is the absolute best water bottle I have ever bought. The BEST. I recommend it to everybody. I can leave it in a hot car all day in the middle of summer 100+ degrees and the water inside would be lukewarm at best. A regular bottle it would be hot. I used to work in a freezer/cooler in a grocery store. Left it in there all day 5+ hours lid on/sealed and the water inside from that morning was still lukewarm, the cooler hadn’t even touched it. The insulation is seriously out of this world. If you work construction or outside its a must. The water can be cold all day. It’s fantastic. Easy to clean although I would suggest washing with vinegar after because soap tends to stick and leave a taste. It’s my favorite water bottle. I 100% recommend over any other brand. Especially for the price. They could charge so much more.

    Die Flasche gefällt mir optisch sehr gut und ist von der Anwendung her perfekt. Ich transportiere damit auch Flüssigkeiten die Kohlensäure enthalten. Funktioniert gut – man sollte aber den Nippel zum Trinken langsam hochstellen und vorher nicht unnötig geschüttelt haben. Die mit 18 und 22 Oz ( 530 und 650 ml) sind für mich am besten geeignet da man sie mit einer Hand umfassen kann und sie passen in die Autohalterung.

    Benutze diese Trinkflasche um meine Getränke lange kühl zu halten, was wunderbar funktioniert. Selbst über Nacht bleiben die Getränke in der Flasche nach kühl.Zudem ist der 2. mitgelieferte Verschluss, 1 Verschluss mit einfacher Öffnung und 1 Verschluss mit Strohhalm, sehr nützlich.
