Stanley Classic Legendary Vacuum Bottle

keeps drinks hot or cold for hours. The wide mouth makes it easy to fill and clean. The sturdy stainless steel build feels durable and great for travel light weight. Simple, reliable, and well-made.

I've never owned a Stanley vacuum flask before, only the other major US brand. I like its classic looks and the pour through 1-piece stopper without any moving parts to disassemble and clean. There were no leaks when I filled it and turned it over. The pour through stopper works well without any splashing. I put the flask through 3 tests: 1. Filled with boiling water and put in a refrigerator for about 10 hours. The water came out not boiling hot, but about as hot as drip brewed coffee. 2. Filled with boiling water, but put in a chest freezer (0 - 8°F) for 11 hours. The outside of the flask was cold and frosted with ice (had some water on the outside when I put it in), but the water inside was still quite hot, almost like drip brewed coffee. I'm sure it would keep coffee hot all day during a cold 🥶 winter outing! 3. Filled with cold water and several ice cubes in the morning and put in a hot car in the midsummer sun 🥵, windows rolled up (got to 104°F that day). In the early evening, noticed the ice cubes were melted, but the water was almost ice cold! I drank some, ran errands, and water was still very cold that night! I'm very impressed with the thermal performance and look forward to putting the Stanley flask to good use, winter and summer! UPDATE: I decided (1) I actually wanted the 1.5 qt Stanley, and (2) being very old-school traditionalist, I wanted it in the iconic hammertone green, a Stanley classic since 1953. The black 1.1 qt Stanley is just fine which I'm keeping (reviewed above), but I reasoned that a larger volume flask would resist temperature changes for even longer (greater volume to surface area ratio. Filled with boiling water and placed in the same chest freezer for 24 hours, its contents were still hot, and hot enough to be very uncomfortable when poured over the back of my hand. This will keep coffee piping hot even after a full day outfoors in our Idaho winter! Filled with ice cubes then topped up with room temp water, there was still ice present floating in ice cold water after 4 days at summer room temp (71-78°F). And that's after pouring out a glass full of ice cold water on the second day and topping it up with room temp water. I'm absolutely certain ice cubes + water would stay ice cold for a few days in our hot summer.

Excellent product, keep my coffee hot for long time

The G.O.A.T. - Stays actually hot overnight, doesn't leak, pours smooth, sturdy handle, and the cup is the perfect size for you to finish it while it's still warm instead of forgetting it on your desk to go cold. I'm a big fan of this Stan

If you're looking for a durable, large bottle this is great! My husband wanted something that keeps his coffee warm longer than an hour that he can sip for hours... the top can be used as a cup, has a handle to be held easily.

Sturdy and keeps srink hot so far for over 12 hours

It seems well made and is definitely big, the only downside is that it wasn’t properly packaged so it was dirty and got a couple minor scratches

Arrived quickly - our old one started falling apart after years of use. This one has a more modern look and works great!
