IRON °FLASK 40 oz Wide Mouth Water Bottle with Spout

The IRON °FLASK 40 oz water bottle is a practical choice for staying hydrated throughout the day, whether at the gym, work, or outdoors. The stainless steel construction gives it a sturdy, quality feel, while the double-wall insulation is designed to keep drinks cold for up to 24 hours without condensation forming on the outside. The wide-mouth opening makes filling it with ice and cleaning much easier, and the straw lid offers convenient sipping during workouts or while traveling. The 40 oz capacity is especially useful for reducing frequent refills, and the Dark Pine color gives it a clean, attractive appearance. One helpful tip is to hand-wash the lid and straw thoroughly to prevent buildup, and make sure the lid is securely tightened before placing it in a bag. Overall, a versatile, durable, and reasonably priced water bottle for everyday hydration.

Beautiful color, love the twist locking cap, holds plenty of water for a few hours out and about, and keeps it icy cold! I don’t even have to add ice when I use my cold water dispenser; it keeps it pretty damn fresh! Has a textured silicone handle thing that helps to hang onto it if it gets a little wet. Doesn’t leak at all for me! My only complaint is it doesn’t fit in my cup holder in the car, so it has to stand on the seat or in a bag big enough to hold it. Considering I purchased the 40oz size on purpose, I won’t take stars off. I knew it wouldn’t fit with the shape! I take this evvvverywhere with me. I have a concert tote that I put this in and even filled up, it doesn’t feel crazy heavy. Fits just right!

I have now owned this Iron Flask for approximately 5 years!! It has a few dents and scratches from dropping it so many times. It stays cold for more than 24 hours and maintains ice for 2.5 days.... I truly love this product!

This Iron Flask 40oz insulated water bottle was exactly what I was looking for. I work in public safety and am not always near the station to refill my water bottle and wanted something that would allow me a couple refills but keep the water cold until I needed it. This does exactly that.I used a 20oz shaker bottle as a water bottle, so this gives Iron Flask bottle gives me two refills until I need to fill it up again. It is the perfect size to keep on my passenger seat without taking up much room at all. I have not had any issues with the bottle leaking and it is very good quality.the bottle came with three different lids. One is just a standard lid that stays attached to the bottle when unscrewed and is stainless steel. There is a straw lid, with a silicone straw that goes into the bottle and a plastic straw on the plastic lid for drinking. The third is a plastic lid like a standard coffee thermal drinking lid. I have only used the stainless steel lid as I only use this to hold extra water to refill my other water bottle since I add a water flavor to it.All three lids have a handle source for easy carrying of the water bottle.I drop this thing all the time and it still holds up really well. Of course it is going to scratch or dent when you drop it, it isn't a magic water bottle. But it has not affected the lids or seals in any way. I like to put stickers on my metal water bottles anyways, so nothing a fun sticker cant cover up!I do not put hot liquids in this water bottle, so I cannot speak to how well it keeps liquids hot, but it keeps my water nice and cold so I wouldn't have any doubt in its ability to keep liquids warm for as long as it says.I would purchase more of this product in the future if I needed.

After my old water bottle started chipping and showing its age, I knew it was time for a replacement. I had been a loyal Zulu user for years in both 24 oz and 40 oz sizes, but when my most recent one began peeling, leaking, and shedding residue from the spout (despite regular cleaning), I decided to explore other options. I’m genuinely glad I did—because the IRON °FLASK 64 oz has been a fantastic upgrade.⸻What I Was Looking ForWith so many bottles on the market, I narrowed my search to a few non-negotiables:• At least 40 oz capacity (64 oz preferred)• Stainless steel construction• A spout-style lid (no straw) with a secure closure• A strong, comfortable handle for carrying• A proven track record with a minimum of 20K+ reviews and 4+ starsIRON °FLASK checked every box with ease.⸻Design & Build QualityThis bottle feels solid, durable, and very well made. The stainless steel construction gives it a premium feel, and the wide mouth makes filling, adding ice, and cleaning simple. The spout lid is exactly what I wanted—secure, easy to use, and no straw to deal with.⸻Capacity & PerformanceThe 64 oz size is perfect for all-day hydration. It keeps drinks cold for hours and eliminates the need for constant refills, whether I’m at home, working out, or on the go.⸻Ease of UseThe handle is sturdy and comfortable, even when the bottle is full. The lid closes securely, giving me confidence that it won’t leak in a bag or during transport.⸻Pros• Large 64 oz capacity for all-day hydration• Durable stainless steel construction• Spout lid with secure closure (no straw)• Comfortable, sturdy carrying handle• Wide mouth for easy filling and cleaning• Excellent reviews and outstanding value for the priceCons• Large size may not fit standard cup holders (expected for a 64 oz bottle)⸻Final ThoughtsThe IRON °FLASK completely exceeded my expectations. It delivers on quality, durability, and functionality at a price that’s hard to beat. If you’re looking for a reliable, high-capacity stainless steel water bottle with a spout lid, this one is an easy, confident recommendation.

I ordered two of these after a recommendation from a friend who has had his Iron Flask for many years and loves it. I got a black one for my husband and a hot pink one for myself. They each came with different mouth piece options which is a nice touch so you can get exactly what you want (I’m a straw girl). My only complaint is this: I think my pink one is defective. The black one holds ice for days, does not leak, keeps things at temp as it should even when it’s just cold fridge water without ice, it’s a 10/10 water bottle. The pink one will melt full of ice within a few hours. It is incapable of keeping anything cold for more than an hour. The pink one condensates on the side when it has a cold drink in it and gets everything around it wet - the black one does not at all. The pink one leaks when tipped on its side. It’s very frustrating because we both use our bottles frequently and usually at the same time (e.g. beach vacations, soccer games, yard work, etc). I find myself stealing his to use when he’s not or we just end up sharing his because my water gets warm. I originally bought this for giving birth to my second baby to have ice water on hand at all times during unmedicated labor and birth (it ended up leaking all over me because I couldn’t sit up all the way to drink so I ended up drinking out of a room temp regular plastic bottle, talk about an annoyance!). I knew my husband would want one so I bought him one as well. I’d like to get another one, the pink makes me very happy. It’s a bummer because this current one I have will likely just go to Goodwill because we’ll never use it. Feels like a waste of money. I’m pregnant with baby #4 now and we’re in a heat wave so I’ve been toting my husband’s bottle around with me everywhere to help me stay hydrated and cool chasing around my three littles. All in all - a really great bottle that hits all the marks and will last forever if you don’t get a dud! I’m not sure how frequently one like that goes out but hopefully not often!

I really love this Iron Flask. It keeps my water cold for hours, the colors are beautiful, and the overall quality feels durable and well made.The only downside for me is the size. The 64 oz bottle is much larger than I expected, so it’s not something I enjoy carrying around every day. I originally bought it for track, and it was perfect for that since I didn’t have to refill it often. For everyday use, though, it’s just more water bottle than I need.Overall, I’m very happy with the quality and performance. If you’re looking for a large insulated bottle for sports, outdoor activities, or long days away from a refill station, this is a great choice. I just realized I personally needed a smaller size.

Best water bottle I've ever owned! It's really easy to clean and you can pop the spout off to clean underneath it, which you should... It keeps my drinks cold for 18 hrs. The coating is great and very durable. There is a cool silicon base you can get for the bottom, strongly recommend. There is also a braided handle you can get.

düzenli su tüketen, su alışkanlığı kazanmak isteyen kişiler için en uygun ürünlerden,asla pişman olmazsınız. Termos özelliği de gayet iyi

This is a must buy water bottle I'd highly recommend it in my opinion I've used it now more than over a year and it has been wonderful put a bunch of ice cubes in it and keeps my water or any liquids in it cold for a good amount of time couple hours or more depending upon how much ice you put in it. I love the black colored marble look. 40 oz is a good size that holds a lot of water used it for playing basketball and other sports and exercise. It got hit by the ball one time and fell over on the concrete and it only minorly scratched it seen in the picture not too bad overall strong durable stainless steel water bottle easy to clean and dry and I love the different head attachments that come with it for whatever meets your preference. I use the twist open top that's my personal favorite one that I always use. I imagine this water bottle will last me years before having to ever purchase another one maybe forever but going from plastic to stainless steel is a must I had enough of plastic ones doesn't keep your water cold is toxic with BPA chemicals and isn't good for your health glad I finally made the switch over to stainless steel and will never go back. Also doesn't leave strange after smells like the plastic water bottles would.

Absolutely love this bottle. Durable, easy to use, no scent. Good quality. Does not leak, seals very well. Keeps water cold for hours sometimes days depending on if frozen

Kanne.Halt sehr lange heiß bis warm.Und ist zudem auch noch robust und lässt sich leicht reinigen.Es sind drei verschiedene Verschlüsse bei, der eine ist einfach nur ein Drehverschluss mit einem Ring den man an der Kanne befestigen kann damit der Deckel nicht runterfällt oder verloren geht.Der andere ist so ein breiter fester einklappbarer trink saug halm, sieht ausgeklappt etwas aus wie bei den Schnabeltassen von damals, auf der Unterseite ist ein Kunststoff Strohhalm den man auswechseln kann, was ganz einfach geht, ein Ersatz Halm ist dabei.Eingeklappt ist es auch dicht, es läuft nichts aus, schon paarmal benutzt.Der andere Verschluss ist so ähnlich wie bei diesen Coffee to Go plastik Bechern deckeln.Und auch ein Klappverschluss dabei der dicht hält.Hab ich bisher nur einmal probiert weil mir diese Art des Trinkens nicht gefällt.Alles in allem bin ich sehr zufrieden mit der Kanne und bereue den Kauf nicht.

Esta excelente, mantiene el agua fria, los hielos tardan en deshacerse ,lo recomiendo, no he checado con agua caliente su duracion , pero si lo recomiendo para agua fria
