Yeti Rambler 20 Oz: The Best Stainless Steel Vacuum Insulated Tumbler

From hot coffee to cold drinks, this Yeti Rambler Bottle did an excellent job locking their temperature. Besides the exclusive heat locking features, this bottle comes with many features that I’ll discuss in the following sections.

Build & Material: Double Wall Vacuum Insulation  

This tumbler is made of 18/8 stainless steel, kitchen-grade stainless steel that can withstand any adverse situation.

Again, Yeti was kind enough to over-engineering the wall into double-wall vacuum insulation. With this shatter & rust-resistant double-wall, you can use this tumbler roughly. The robust design gives this bottle an extra boost in terms of appearance. However, magnetic technology is more exciting than the outer look.

You can keep your hot coffee hot and cold drinks cold for a long time – with the help of this magnetic heat locking technology. Also, the magnetic slider lid gives a good feeling while opening & closing. Talking about Yeti 20 oz tumbler dimensions, it’s 6 and 7/8 inches in height and has a lip diameter of 3 and 1/2 inches.

Though this size is a perfect fit for standard cup holders, it won’t fit in a small cup holder.

In summary, this tumbler is built to tolerate any situations, and the Duracoat colors help enhance the overall appearance and make it more rigid. However, you might think about cleaning a cast iron cookware, right?

Duracoat Color: A Beauty & Sturdiness Solution 

As I mentioned earlier, Duracoat color gives this tumbler extra boost when it comes to outer appearance and build quality. This color coating is rugged enough to stand against anything thrown at it, and withstanding the unpleasant situation while hiking or adventurous outdoor exploring.

This tough as hell bottle is ideal for road trips, home use, and outdoor exploration – thanks to its super sturdy build quality and Duracoat colors. Besides everything else, I haven’t faced any issue of colour regarding peeling, fading & cracking in my three months of usage.

Be Lazy: Completely Dishwasher Safe 

Yeti doesn’t want you to waste your time cleaning bottles. So they made this tumbler completely dishwasher safe.

Now you can wash and clean your bottle with minimal energy & time, resulting in more outdoor exploration time.

Though this bottle is dishwasher safe, I recommend cleaning it casually with your hand. Because cleaning with a dishwasher may harm color coating – if used daily.

Whether you clean it with a dishwasher or hand, you won’t feel any mixed taste after switching from drinks to drinks.

Heat Locking Durations – Hot & Cold 

The first and foremost duty of an insulated tumbler is locking the temperature – hot or cold.

An ideal tumbler will keep your cold beverages cold and hot drinks hot even until the last sip. Fortunately, I have had an excellent experience with yeti rambler bottles – as it kept my hot coffee hot until the very last drop of it.

Though I needed my coffee to be hot for 1 to 2 hours, I’ve performed a few experiments so that I can give you an estimated heat locking duration of hot & cold drinks.

So, hot drinks like coffee remained hot for up to 7 hours. Again, cold drinks remained cold for 2 hours. Note that temperature will continually decrease with each time you open this yeti 20 oz tumbler lid for a sip.

How Does This Insulated Tumbler Works?

An ideal tumbler can reverse the natural trait of hot/cold drinks with the power of science. In our yeti rambler tumbler case, they use magnetic technology to lock and hold drinks’ temperature for an extended period.

Also, the double-wall stainless steel helps with the overall heat locking technology.

The most beautiful thing about a tumbler is, the outer atmosphere doesn’t affect the inner part – resulting in long heat locking duration.

Again, Yeti claims their bottle can withstand triple-digit heat keeping hot drinks hot and cold drinks cold.

Whether they tell the truth or not, I have no complaints regarding their heat locking technology & claims as I’m getting my coffee hot even after 2 hours of journey.
