Not sure if everyone saw the FB video that was around recently. Someone did a scientific study of the 3 mugs (Yeti, Ozark and RTIC) similar to one that was posted earlier in this forum. It mirrored the results almost to the end.
The basic concept was that they filled all of them at the same temp, with the same amount of ice and let it sit. The Ozark came out on top with ice still in the cup at 56 hours. Yeti was second and I cannot remember when the RTIC ran out of ice (40-50 hour range, I believe)
My only concern - I have never needed to keep a drink cold for 2 days - it is usually refilled multiple times by then..... to each their own though.
As for the cooler - looks great. Where did you find it?
