IRON °FLASK Tenting & Climbing Hydration Flask with 3 Lids – Stainless Metal, Double Walled & Vacuum Insulated Water Bottle – Leak Proof & BPA Free (Cobalt, Straw – 64 oz)

A flask that gets the job done!
This is a great flask that’s very durable and flexible.This is my second flask from this same company and I’m always impressed by the quality. My original 1 gallon flask lasted me for years and was very solid. I went with this smaller flask because it’s much easier to carry around while still holding a good amount of water. During the summer in the peak heat it always keeps the water crystal cold and it helps tremendously for my outdoor job. I’ve always loved the colors and designs and the three interchangeable lids are a game changer for me.

Love!
I love these bottles! This is my second one. They’re pretty much indestructible and have a perfect surface for stickers. They keep water cold forever, keep ice frozen over night. The design makes it easy to get a big drink of water to take meds, it’s easy to open but stays closed. I love the color options, too!

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.

Awesome Water Bottles
This is my second Iron Flask and I love it! They are such great quality and keep your drink cold all day. Way cheaper than other brands too. I use this at work, at, home, on the go, for everything! I have to watch my water intake and this big one help tremendously. I love this brand and have so many of they bottles!
