Running from sizes 14 oz to 64 oz, this tumbler keeps drinks cold for 8 hours. All of the tumblers had the same 27 ounces of crushed ice and were placed in the sun in a straight line so all received the same amount of sun, heat and breeze.

Neither is Ozark Trail, so I’d be careful tossing them into your bag. Even though both claim to be leak-proof tumblers, I held both upside down and they both leaked a lot! Because of the handle, for example, you won’t be able to put them into the side pockets of a backpack either. I started by filling each cup with 15 ice cubes, set them in my kitchen with the lids on, and started the clock. The Ozark Trail Multiforce Multi-Tool is an essential companion for outdoor enthusiasts, DIYers, and everyday tasks.
This Ozark Trail 30 oz Insulated Stainless Steel Tumbler ozark trail tumbler with Swivel Handle is one of my new favorites! It has a leakproof lid, a carrying handle, and it holds 30oz of liquid! Whether you are going on a field adventure or driving to work, a favorite drink in the morning is indispensable.

It’s claims to be BPA-free and has a “no sweat” design, which keeps fingers dry.
With a 40-ounce capacity, this reusable tumbler is the drinkware everyone needs in their pantry. Double wall insulation and double wall lid keeps liquid hot and cold longer. This tumbler kept beverages cold for nine hours (longer than any other vessel we tested). And its straw lid ozark trail tumbler creates a tight seal that prevents most leaks. But it comes in a limited number of colors and sizes, and it has a straw lid only.
