The Yeti tumblers are so cool they’re on fire (is that even possible?), and SeaSucker has gone the extra mile to make sure your favorite drinkware is secure on the boat. Instead of letting your tumbler flop around in a standard 3.5″ cup holder, our new Tumbler Adapter Insert gives your tumbler (Yeti, yes, but also many of the copycats and emulators too) the gentle but snug caress is deserves.

This item is just the Tumbler Ring and does NOT include the cup holder insert. This Tumbler Ring is sized to perfectly fit the cup inserts used in SeaSucker cup holders – other brands and styles might not match.
