"With our car cup holder, your bottle can be held in place firmly.

The expander fits most car cup holders, which can hold large bottles, mugs and other big drinks with a diameter of 3.4-3.8 inches.

It is compatible with Yeti 20/26/30 oz and Mug 10 oz, Hydro Flasks 32/40 oz and Mug 6/12 oz, Stanley Travel Tumbler 20/30 oz, Nalgenes 30/32/38/48 oz, Camelbak 32/40 oz.

The features include an expandable base that can adjust to fit different kinds of automotive cup holders from 2.5-3.75 inches in diameter, fits perfectly in most vehicles, trucks, RVs, boats, golf carts and strollers.

There are three rubber tabs (removable) on the inner wall which make cups/bottles/mugs more stable during driving, easy to insert or remove bottles from the adapter without pulling the adapter out of the car's cup holder.

The rubber coaster on bottom helps prevent bottles from rattling or sliding while driving.

The extra thick pads on the ends of the expanding legs are soft enough to form to the shape/angle of the walls of the existing cup holder, yet firm enough to provide stability.

The U-shaped groove allows a cup or mug with a handle to be used in the adapter without tilting or splashing.

Just twist the base of the adapter to expand or retract the base and it can be firmly fixed on the car cup holder."
