A great addition for any coffee or road trip - Rocky Mountain Tumbler
If you’re planning a day on the beach or a long car ride, you need a way to keep your beverage of choice icy cold. How can you ensure that you always have a refreshing drink at hand? And what’s the best way to keep your coffee or tea warm in the winter months? An insulated tumbler is the answer which is probably why you have landed on this Rocky Mountain Tumbler review.
But tumblers come in many different designs, shapes, and sizes. How do you know which one fits your needs the best? The 30 oz. Rocky Mountain Tumbler is a popular option. Let’s look into its main features and see if it actually works.
What is the Rocky Mountain Tumbler?
This stainless steel tumbler can hold 30 ounces of liquid, which makes it a great choice for road trips. Unlike a thermos, the Rocky Mountain Tumbler fits into most cup holders.
It even has an anti-sweat design that makes it easy to hold securely. You can even use this tumbler while you drive. There’s a see-through lid that keeps it from leaking or spilling.
However, thermal insulation is the most important feature to look for in a tumbler. This product is designed to keep hot drinks hot for 12 hours, while cold drinks are supposed to stay cold for 24 hours. So does Rocky Mountain deliver on this promise?
Is the Rocky Mountain Tumbler Made in USA?
No, these tumblers are made in China.
How Does the Rocky Mountain Tumbler Work?
The thermal insulation comes from the double-wall vacuum design. This tumbler has a pair of steel walls separated by a vacuum. This vacuum prevents heat transfer between the two walls.
If you’re using your tumbler for soup, tea, or some other warm drink, the heat will be trapped on the inside wall. On the other hand, you can use it to store the icy drink of your choice. The vacuum will keep the heat out.
There’s very little heat transfer but the heat exchange is not zero. This is because heat radiation is still possible in a vacuum and the lid is not as well insulated, so your drinks won’t stay cold or hot forever.
The Rocky Mountain Tumbler Features
Here are the main features that make this tumbler a useful option:
Double-wall insulation
While the insulation probably won’t really last a full day, this tumbler is a great option for both the summer and the winter months.
Practical design
The bottom half of the tumbler is narrow enough to slide into most cup holders, so you can have the tumbler at hand when you’re driving.
BPA-free stainless steel
As it’s made of stainless steel, this tumbler is a durable choice for camping, mountain-climbing, and other adventures.
The Rocky Mountain Tumbler is BPA-free, which means that you won’t have to worry about a metallic aftertaste. Since the health effects of BPA are still being studied, it’s definitely safer to stick to products made without that chemical.
See-through lid
With other tumblers, you may find it annoying that you can’t tell how much of your drink you’ve got left. The Rocky Mountain Tumbler’s see-through lid makes it easier to keep track of your beverage. In new condition, the lid’s silicone seal is spill-proof.
Is the Rocky Mountain Tumbler Dishwasher-Safe?
No. While you can safely wash the see-through lid in your dishwasher, the steel tumbler needs to be hand washed.
