IRON °FLASKClassic Tumbler - Vacuum Insulated Stainless Steel Water Bottle, Double Walled, Drinking Cup, Insulated Travel Mug (Blue Waves, 32 oz Solid Lid)

Very nice tumbler. Husband takes coffee to work in it. Stays hot for a long time and does not leak!!

I received my 32 oz. "Dark Rainbow" (pretty!) IRON °FLASK tumbler yesterday and feel compelled to write this review to encourage you to get your own NOW! I live in the sultry south where heat and humidity will turn your ice-filled glass into a watery drink within minutes. Initially, I bought this to use as sort of an "individual" ice bucket so I could refill the ice in my glass of tea without getting up every five minutes of a Prime-binge, especially any compelling thriller. Indeed, for the first night of having this beauty, that is precisely how I used it—and it worked perfectly. At the end of the night, I left ONE lone ice cube in the tumbler to see how it would fare. Twelve hours later, that solitary ice cube is only partially melted and still icy cold! The tumbler itself comes with two straws, and two lids: one for use with a straw and one flip-top for use with hot drinks (or if you just prefer to drink directly from the tumbler). Each top is very thick—I've never had a tumbler where the top is designed to also provide insulation. All-in-all, I am very impressed with the quality and functionality of this tumbler. I only write reviews when I am deeply disappointed with a product to serve as a buyer-beware herald, or am over-the-moon pleased and what to provide fellow shoppers to confidently purchase. Happily, this tumbler is the latter.I haven't tried it in my car's cupholder as yet, but believe it will easily fit there as well. Also, there was ZERO condensation when the cup was filled to the brim with ice and none when I checked that solo melting ice cube this afternoon. I love that I can place the cup on any surface without worrying about damage to the finish.NOTE TO MANUFACTURER: I still would like to find a mini-ice bucket (48-50 oz. would be ideal, and not more than 5" diameter) to use when I just want to drink from a glass, and don't want to haul out my big ice bucket. I am convinced that YOU are the manufacturer to create the perfect mini-bucket for a chair-side refill. I would gladly be your first customer. Thanks!

I like everything about this cup. Perfect size (20oz) for me, keeps coffee hot forever (nearly), when the flip top is open it is out of the way of my nose, when closed it absolutely prevents leaks and the mechanism itself is easy to clean completely - nothing is trapped - and easy to open and close.

I wanted a nice new water bottle to help me drink more often that didn’t look like the current popular style with the handle. This is definitely worth its value. It keeps my drinks cold even when it’s sitting out in the sun. It’s very durable with my clumsy butt having dropped it many times and even left it on my car roof then started driving. All it cat were a few scrapes in the color and a small dent. It still works great.When using the straw top it is not entirely leakproof as water can come out the straw and sometimes a bit around where the straw is inserted but this is to be expected.My mom loved mine so much she got one and then her husband liked hers so got one aswell along with the companies smaller coffee mug version. I even saw my uncle at a family reunion had another style water bottle from Iron Flask!I definitely recommend!!

It’s made from quality steal. The lid with the small hole & straw is thick to keep it cold and has ONLY enough room for the straw in case you tip it over. It is doubly awesome because that straw hole is small enough to allow me to easily put my finger over the hole and shake up my drink when I use a powdered drink instead of stirring with a spoon (doesn’t work well) or using the other top to shake it when I want to use the straw top. The other lid (flip top) is also well made and has a fairly small sip hole which also prevents BIG spills and can also be used with the straw. I haven’t had any leaking from the flip top lid or from any of the seals around the edges. It is metal and if you dented really badly that might prevent a seal. I love the outside surface- it’s beautiful and it has a matte surface so it will NOT easily slip in your hand and it does not have any condensation from icy cold beverage inside.This is one of my FAVORITE purchases ever from AMAZON- I rarely review anything and I do not give fluffy slanted reviews- if it’s good exalt it. If it’s bad, I burn it to ashes. Honest reviews only.

I’m giving this tumbler 4 stars because it doesn’t hold 20oz when you put the lid on. It can only really hold about 16.8oz. I was curious so poured a standard sized 16.8 bottle of water in and it came up just above the inner groove where the lid sorta ends up after screwing it on. The lid is very thick and helps keep drinks cold, but at the cost of oz of liquid. Other than that, I love this tumbler. It keeps my drinks cold through the day. The thick lid hasn’t leaked either. It’s very easy to clean too.

Iron Flask is my favorite insulated tumbler now. I use the flip top lid most of the time and it is definitely leak proof. I can put it in my bag full of water and know it’s not going to leak. Even when I do occasionally use the lid with the straw, it is also leak proof. It keeps my water cold for many hours, fits in my cup holder, and is reasonably priced. I will more than likely be buying more Iron Flask tumblers because I highly recommend them.

Love them. I have learned ver the years I should never be allowed a coffee or water cup that can be easily broken. These are fantastic. Light, sturdy and easy to carry. They passed the leak test. I have wrist damage so dropping things is normal, and so far they have survived. I love both the choices in color, and how great they looked when I got them. I gave the darker blue to boyfriend and he loves it. The lidds are easy to get on and off, and I love that they give is both types. Works exactly as advertised and I couldn't be happier.

Beautiful non slip finish, fits my car perfectly and keeps what ever is inside either hot or cold for hours.

we liked the flask, great for travel with hot or cold beverages,leak proof skid proof,a great product

Bought fur a cruise! Holds 2 pina colada's by the pool in hot sun and stays ice cold for so long!! Highly recommend

I am a nurse and I like to have coffee all day and I LOVE this mug. It keeps coffee warm for over 5 hours and the colours are beautiful. I love that it comes with 2 lids and I’ve never had any problems with leaks
