Make your tumbler accessories more versatile with our Tumbler Boot Adapter! This stretchy band fits snugly around the bottom of your 40oz standard-size tumbler to adapt it for 3.25" shorty boots or to convert standard-size boots for use on the 32oz HydroJug.
At just 3/8" tall, the adapter adds the perfect lift and grip for a secure fit without adding bulk. Need extra adjustment? Simply stack multiple adapters to fit tumblers with narrower bases.
