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

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.

Great price, keeps it very cold for days!!!, and great size. It might not be your typical brand but it works just as great! Do be careful, although it’s a great cup and keeps everything cold af, it will dent if you don’t take care of it properly or if u drop it really hard. I lost one cup at worked, dented another pretty bad, but 3rd times a charm.

This is the 2nd time purchasing this product. After 2 years I lost the 1st one but can tell you this product is extremely well-made, keeps ice overnight and liquids nice and cold. Never chipped, color never faded, and the cap and straws remained intact. Would recommend to all.

Keeps liquids cold or hot for a long time. Love the variety of lids. Very durable

Great product! Flip up straw works smoothly, everything looks of great quality, keeps ice all day! Bargain at around $20. Why buy a $30 bottle?!

I have been using a couple of Contigo water bottles for the past few years (a 24 oz. and 32 oz. Ashland Autospout), and I really liked them. However, they are not insulated, so will collect condensation on them when filled with ice water. I decided to get the Iron Flask because I know somebody who has one and likes it. I purchased the 40 oz. black bottle. I can fill this bottle with ice and cover the ice in water, and the ice will still be there 8-9 hours later, but only if you're not drinking out of it (I left ice water in it over night just as a test). If you are drinking from it occasionally, the ice is more likely to melt a little faster. Condensation has never formed on the outside of the bottle. The wide mouth is pretty much par-for-the-course for metal bottles; my Contigo tops actually fit well on this bottle. My MSR MiniWorks EX is a little more of a snug fit, but it still fits enough that I feel confident that I could use the two in concert to procure water outdoors. I have also purchased the Iron Flask paracord handle, which makes the bottle easier to carry. I do see some room for improvement, though not with the bottle itself, which has been working out great so far. My complaints are mostly with the straw/spout lid (which is the only one I use), and most of those I only really have because I am comparing it to my Contigo lids. The old Contigo Autospout lids were better in almost every respect; they had a lower profile, they were more watertight, they had a more rigid straw, and you could operate them with one hand. The Iron Flask lid often has to be set on a surface to be opened with one hand. Having a springy spout with a button-operated catch is a much easier and more convenient system to use one-handed. The loop on the spout lid is also just about perpendicular to the long axis of the bottle, which makes carrying it in hand or attaching it to a backpack a little more cumbersome than a design with an more steeply angled loop. As mentioned above, I purchased the paracord handle, and that makes this bottle significantly more convenient. The air inlet on the lid is plugged by a small post that is molded into the drinking spout. This is enough to keep water from pouring out when the spout is closed, but if the bottle is laid on its side, there will be some minor seeping over time. Something like an umbrella valve might make this problem go away. The last problem I have is the straw is not quite as rigidly fixed to the top as I'd like. If you fill up the bottle with ice, it is harder to jam the straw all the way to the bottom because it is held to the lid with a flexible fitting (looks like silicone, maybe). The Contigo straw was less likely to wobble around as you pushed it through the ice, which meant it was easier to put on when the bottle was filled with ice. All in all, I'd say the bottle is very good, but the tops are a little lacking. I would simply use the tops to my old Contigo bottles if they had longer straws that went all the way to the bottom of the bottle, but they don't. Iron Flask should seriously consider creating something similar to the old Autospout lids (or even just licensing the design or something). Even if they sold it separately, I think it would be an excellent addition to a very good bottle.

My ice does not melt even after leaving the thermos inside a closed up car all day where the temperatures get up to 105° outside and about 170° inside. I still have ice cold water after it sat there for 12 hours. Pretty freaking amazing.

Well made and kept water cold while hiking!

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.

Bardzo dobrze trzyma temperaturę, wymienne zatyczki też bardzo użyteczne i szczelne

A great bottle. Very happy with the purchase and service. Thank you

Robusta e di buona fattura. Mantiene sorprendente l'acqua fresca nel tempo. Consiglio.

Great
