The pelican is just perfect for traveling; it is stylish and performs incredibly well. Judging by pelican hard coolers, we had expected it to top the list here but the rambler, Ozark and Engel lasted it out in the ice retention bout. This is not to say it has poor ice retention cause it held ice for up to 24 hours.

Unlike the Yeti Rambler, Ozark and Engel tumblers, the pelican boasts it complete production in the USA. Double-wall vacuum insulation and the inner wall coating provide increased ice retention.

It narrows down at halfway down which allows it to fit into any cup holder. The highlight of the tumbler is the strength; you will get many years from this model.

Insulated Tumbler Buyer’s Guide

The tumblers mentioned in our list were picked following all the factors will be included in our buyer’s guide. In essence, the models mentioned on our list are to our knowledge the best on the market. And what’s more? We update our inventory with better products as they emerge in the market.

However, this buyers guide will help you in the event you want to find a product that has ticked the boxes of what an ideal tumbler should have to be worthy of buying.


It’s a two-way street – a tumbler should maintain cold drinks just as much as they can keep hot beverages. This means it has to have high insulation around the walls, and the lid has to be correctly sealed to increase the performance. The best tumblers employ double-wall insulation and are vacuum shaped for improving insulation.


If you want a tumbler that will last many years of use, as I guess you do. Then all the cheap plastic tumblers that sell at $5 will not make the cut. You should go with brands that utilize stainless steel construction on their products.

Other components, like the lid and gasket, are essential. Pick a cover that is spill-resistant and ensure that the gaskets are of excellent quality. You don’t want the situation where after a few washes, the gasket warps or slacks.


Now, this is subjective to every user. We picked the 30 oz because they are the most used tumbler on the market. They hold a standard capacity that caters for the average users need. However, when it comes to buying a tumbler, you can’t just go with popular demand. It is crucial to pick a size that will cater to your daily needs.


Finally, if you’ve read thus far, we believe you’ve garnered significant knowledge that will help you make an informed decision on tumblers when you are in the market. Our team had already selected the best options online, and you should not have any problem picking from these options.
