IRON °FLASK Camping & Hiking Hydration Flask with Straw, Wide Mouth Insulated Stainless Steel Sports Water Bottle - 18 oz Blue Waves

The Iron Flask is an excellent product, especially for the price! Great construction, cute clip on the handle, and most importantly, it keeps the ice in my water clfrozen overnight!I love the color and it's the perfect size. It came with a straw brush and an extra straw. I would absolutely buy this again, but this thing is so solid and well-made, I know it'll be around for a good while.

This bottle is great! It keeps things relatively insulated, and honestly is a good shape for its size. I mainly just wanted a large bottle that I could just fill once a day, and this did the job great. Super durable after many drops outdoors, no visible leaking and easy to carry if you get the paracord thingy too. Would recommend, especially if you get it for $20 like I did.

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.

Im a delivery driver for a major big box store (groceries and the like). This bottle is absolutely amazing. Its large enough to keep me hydrated all day. It keeps my water cool all day even when exposed to high heat and sunlight. It is super durable. It does not leak at all. I love it!!!! I would recommend it to anyone.

The Iron Flask is hands down the best thermal water bottle I’ve ever owned. It keeps my water ice-cold for over 24 hours and my coffee hot for hours. The insulation is incredible, and the quality is top-notch.The bottle feels sturdy, doesn’t sweat, and comes with multiple lids, which is super convenient depending on how I want to use it. Plus, the design is sleek and modern—I get compliments on it all the time.Honestly, it’s perfect. No leaks, no weird tastes, just performance and style. Highly recommend!

Very good and it can hold the temperature up to 3 hoursThe bad side was that the lid started to get moldy after 2 months

After having funky water bottles of various sorts, I finally got this in the 18oz. and am very glad. I plan on this one being my last, unless I get a 40oz. or one with a handle on the side or a flask shaped one. I love having the three different ways to drink the beverage, which is perfect for picky people like me. One water bottle, three different lids, that's smart, instead of getting a different water bottle for every type of lid, lol!!! I was going to get the 22oz. but the 18oz. is really more perfect for me. I got the ivory one and the white boot, and the ivory is a bit too yellow for me, but the white boot tones it down a little, and overall this water bottle looks sophisticated. I'm giving my old, cup-style one to goodwill. For water, the only bottle I have which competes with this one is a glass whiskey flask from the liquor store. The glass flask is thick glass, the lid doesn't leak, and the flat shape fits into backpacks and such much better than a round bottle. So, I will be keeping that and continue to use it, while using this one for coffee or any beverage which I want to keep hot or cold. If this came in a flask shape, that would be great, too, or a version with a handle on the side. I'm so glad I got this and that there are mooaar sizes available, too!!! Love this and I highly recommend!!!

Love this bottle. Keeps ice pretty much all day and not much melting at all. Holds plenty of fluid and the straw drinking option is fantastic to use. The carabiner hanger is nice, and I also added a paracord hanging accessory to it, so it gives me options for carry or keeping in my vehicle when driving. I use this every day and works great and is very high quality. I looked at other brands and never had an Iron Flask brand but will certainly buy this brand again.
