I got one of the Yetis about 2 weeks ago. I love it. It holds a 12 oz. GATR AID pretty good too.
See what I did there?
A friend of mine showed me a photo of his friends truck. It had caught on fire & was a total loss. The owner went up to the, took the cup out ( with gloves), removed the lid & there was still ice in the cup. Seriously.
Lady at work has one & says her coffee stays hot for 6 hours.
They are a little pricey but we'll worth it.
