Patent Pending adapter is perfectly sized to quickly adapt your favorite 12 oz stainless steel koozie (such as Yeti, Rtic, Ozark Trail and more!) to hold your favorite 16 oz beverage!
Great for 16oz cans of energy drinks, sodas, and even domestic or craft beers… You name it!
No need for multiple koozies, as the adapter lets you switch between 12 and 16 oz cans in no time!
In-house testing has shown that after an hour in 90deg heat, the temperature of the beverage only rose 3 degrees (compared to a 30degree rise for neoprene type koozies)
