Do you want a drink to stay COLD during the heat and not have your ice melt? I think everyone has been in this situation where you go to take a sip after a couple of minutes and all your ice is gone. Your drink is starting to get warm and you just want to pour it out ohhh gross.....Fear Not.
Companies have been embarking over the past couple of years to make tumbles that will withstand the heat and keep your drink ice cold all day. 
YETI
Yeti has been designing coolers since 2006 because most coolers would not withstand the torture that us outdoor people would place on them. Most people they say had to purchase new coolers every year due to broken wheels, handles, or tops. So these brothers invented the YETI Cooler.
They now make these tumblers, cups, and can koozies.
- 18/8 Stainless Steel
- Dishwasher Safe
- Double Wall Vacuum Insulation
- Custom Designs are no available
- Multi Colors or Stainless Design
Yeti's are $19 and up depending on the size and shape that you want
OZARK TRAIL (WALMART)
For those thrifty one's of us who don't need to have a brand name came the Ozark Trail Tumbler.
These are sold at Walmart at a lower cost of a Yeti. You can find these in the camping section of your local Walmart.

So I purchased a Yeti and an Ozark Trail Tumbler and placed a cup of ice in each tumbler and let it sit in my camper when the thermostat said 75 degrees with the lid on each. Placed each tumbler on the kitchen counter and let them sit.
After 4 hours I checked each tumbler and found out that they each had approximately one teaspoon of water from the ice that melted from each cup. I decided to leave them overnight and to my surprise there was not much difference at all in the remaining ice in each tumbler. They tested just about the same.
The next day I decided to put water in the YETI tumbler and put a cup of ice in it. The next morning after 8 hours there was still ice in the cup and the water was COLD! WOW!!!
Decision :
- The tumblers look the same but the YETI name stands out on their tumbler.
- Both the Yeti and the Ozark say they are made in China.
- If I use these for camping I do not have to worry about the Ozark not being dishwasher safe
- Love both of these tumblers because they do not "sweat"
- If you choose the YETI or the Ozark you will get the same concept without the brand name price.
- So I could not choose just one so I chose them both. I have multi colored YETI's and Ozarks for each of my kids. I also purchased the can Koozies so we can have adult beverages that will hold cans of beer..etc. I am sad that no company offers a smaller size Koozie that will hold my Lime o Ritas...maybe someday.
