IRON °FLASK Camping & Hiking Hydration Flask with Straw, Wide Mouth Insulated Stainless Steel Sports Water Bottle – 40 oz Midnight Black

great product
This is an amazing cooler or flask or water bottle, whatever you want to call it. It keeps your drinks cold for at least 24 hours. My wife left it in the golf cart at the course. I picked it up the next day and the ice was still solid it did not melt. Now you could buy a couple of other water bottles from some of the name brands and pay at least twice what you are paying here, but you would not be gaining anything. The only difference is that you cant put a design on this. However the colors are pretty cool. I think i would rather save a few bucks and live without the design. I love this water bottle/ flask/ or cooler. I would highly recommend this item.

GOOD QUALITY COMPARABLE TO BRAND COSLTY ONES
Best! We have ordered a few of these in different sizes in the past years for school and they last and keep water cold! Comfortable. Love the different options for the lids: canteen, spout, straw.. Highly recommend!

The best review ever.
tldr; I’ve had it for one day, seems pretty good, I support it, if that counts for anything. If you have doubts, take a look at the Aquatix Fliptop mentioned below as it’s a great bottle. I’ll update this review if anything happens (leaking with a seal in place, container doesn’t maintain temperatures, etc.).Update, 3/19/20: I filled my 40oz. Iron Flask with 10 cubes of ice and cold water; the 32 oz. Aquatix with 6 cubes and cold water. I figured the 8 oz difference warranted more ice for the Iron Flask. It’s been 3 hours, and the Iron Flask’s ice is all melted, but the Aquatix is still going super strong, all six cubes are there, albeit 1/2 – 3/4 the original size. If you’re looking for something to keep your drinks cold, the Aquatix is the way to go. But I’m sure both bottles have their merits to each individual person.To begin, I use an “Aquatix Fliptop double insulated vacuum sealed 32 oz.” So why’d I buy this? I live in a pretentious town that thinks its amazing, but the drinking water served everywhere is pretty terrible without a filter. That’s just America these days, and if you disagree, just give it time to reach you, or maybe you’re already acclimated to terrible water and can’t differentiate anymore. I go to the gym, smoke a few j’s with friends and hike, I walk 4+ mi’s and run 3+ mi’s every day, not including sprints. I partake in archery, rock-climbing, and bowling; I’m active AF. So, I thought, if I’m gonna want decent drinking water throughout the day, then I’ll need another bottle. I also thought that instead of spending $100 on White Russians during my bowling leagues, I could just buy the $30 supplies, mix it, and keep it in this BLUE 40 oz thermos. I think 16 oz. would suffice, but better safe than sorry. I checked google for the best drinking bottles; then correlated it with Amazons selection. Thus, here we are with Iron Flask.SO first things first: TEST FOR LEAKS. I’m only going to be using the straw lid, so I tested it out– there’s many notorious reviews commenting on it. I didn’t experience any leaks with that lid. I’m assuming the leaks are probably because these people lost the rubber seal that goes inside the lid, along the rim; or maybe the flip top isn’t closed completely. Secondly, it’s pretty easy to handwash. I just put a little soap in, hot water, and shake it for a few minutes like I’m mixing a cocktail. Could it be easier? Yeah, it’d be nice to throw this into the dishwasher. We can build spaceships, sell $200 phones for $1600, quarantine an entire country because the healthcare system is a joke– so I dream one day we can make these bottles dishwasher safe. Lastly, the styling is amazing. I got the 40 oz “Dark Night” variant, but if this holds out for a few months (if not years), then I can absolutely see grabbing the “Dark Rainbow,” and “Lime,” variants too. They all seem to look nice though.So what’s wrong? They give you an extra straw, three lids, BUT NO REPLACEMENT SEALS. My Aquatix came with a replacement seal, which I actually needed as I noticed it was leaking, and found the seal to be gone. Busted out the replacement and its been going strong for almost a year since. You don’t know what you got ’til it’s gone, and I promise, a replacement seal is very welcome.Hopefully this review helped, it’s a great container. If you have any doubts, I can swear by the AQUATIX I previously mentioned: it’s been solid, dropped dozens of times, still going strong. The best part is that I can put 4-8 ice cubes in it, cold water, and go throughout the day, 6-8 hours, and have it be as chilled as it was when I filled it. I’ve filled it with ice and water before bed, and woken up to the same ice cubes floating around. I capitalized AQUATIX so you know this last paragraph is in regards to the AQUATIX.

One beautiful bottle!
Look at this beauty! That is one good looking bottle.I think it does okay on keeping the ice cold. It’s not a bottle I would consider part of the top tier.But it works and it’s very ecstatically pleasing.I love the 40 oz. I don’t have to fill it up all the time which is awesome. It fits perfectly in my Ram cup holder.Absolutely zero leaks. And I do tend to shake my bottle to get the ice mixed.

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.

Big bottle to help me drink more water, it’s a good size well styled bottle,no leaks
