IRON °FLASK Nomad Tumbler - 2 Lids (Straw/Flip), Vacuum Insulated Stainless Steel Bottle, Double Walled, Drinking Cup, Thermos Coffee Travel Mug, Water - Cotton Candy, 28 Oz

Love this cup! I took this on a trip right after I got it. It ended up sitting in a hot car for 5+ hours and it still had ice in it. So far I've only used the straw lid and while I know it would leak through the straw if tilted that far, I've not had it leak around the straw. I will definitely be buying more Iron Flask cups!

Our household loves all our Iron Flask insulated cold and hot drink carrier cups... The quality of Iron Flask is top notch and worth every penny. We love all the stylish colors offered and they are very durable. When it says 12+ hours cool or hot it's true! They have all been packaged well to prevent any damage. We take these on Vacay with us especially with the pretty Summery ombre colors.

no leaking and love it. Easy to clean

Keeps my coffee hot for hours. Well worth the money.

So far so good. It is keeping my drink cold at least through the day. If you are using it for a cold drink, will keep with ice at least 12 hours, because of the straw, it is not leak "proof "but does have a nice tight fit. If you are using the hot beverage lid....it is leak proof....It easy to hang onto (nice texture), the best I have found so far. (I have tried 5 different ones.)

I want really really badly to give this thing 5 stars. The number of times I’ve fallen asleep with an iced beverage inside and woken up with solid amounts of ice still in it amazes me.The only reason one star was removed is the number of times the closable lid has flung coffee drops at my monitor and laptops upon opening to take a drink.I don’t know exactly how it happens, but it gets frustrating to clean up little coffee stains all the time, and I’m just hoping it doesn’t get inside a keyboard or speaker hole and destroy something at some point.If I remember correctly it comes with a straw lid as well, and I might have to investigate using it more. I hope it allows similar chill lengths, but sometimes I need the full seal when I’m on the go, so the flinging lid has to be used at least sometimes.

Purchased a few different travel tumblers that were at least 20 oz and would fit under my coffee maker. This was the one I kept, since it met all my criteria……20 oz, fit perfectly under the maker, did not leak at all when turned upside down, kept the coffee hot and has a nice feel to the grip. Have not used the straw lid, and probably won’t. Very happy with this tumbler so far. Hope it holds up well. Also, like that it has many color choices.

When I started a new commute with no place or time to stop for coffee, I started bringing my coffee from home. Before I got an Iron Flask, I spilled coffee in my car almost every day - sometimes a little and some times a lot. My new car smelled like coffee all the time. I tried many different fancy containers, and all had one issue or another in addition to leaks and spills. Then I ordered an Iron Flask. All my problems were solved. Even if the tumbler gets knocked over on it's side, with the straw in, it won't spill or spill more than a drop from the straw. I've knocked it over on my desk without disaster. Yes, it keeps my hot beverage hot. My iced coffee has ice still in it at the end of a 10-hour day. Yes, it doesn't sweat on the outside. Yes, the seals on the lids don't leak, even after 2 years of taking it to work 5 days per week. Yes, it fits in your car cupholders. Yes, it comes in 20 colors! This is the perfect container. Never spill your coffee again. My newest car does not smell like coffee, and I have not shed one tear over spilled coffee. The Iron Flask is still going strong. I use it every day. It never causes me grief. It does exactly what it should do and what I need it to do, and based on all the fancy containers I tried that didn't, this container is very special. I keep it clean by rinsing it out every day, including running hot water through the straw, and sometimes using dish soap. I air-dry the pieces on the counter overnight, and it's ready for work the next morning. The best.
