The Swigzy car cup holder adapter is designed for 3.4″-3.8″ diameter bottles and cups. It is the only cup holder adapter with an adjustable base and rubber tabs to keep your bottle secure. The adjustable base is designed to fit most car cup holders (see picture with dimensions to ensure it will work with your vehicle) and adjusts from 2.5″-3.75″ in diameter. Adjusting the size of the base is quick and easy, just turn the cup portion of the adapter to expand or contract the base.

The adjustable base ensures that the adapter will fit snugly into your car’s cup holder. The one-piece design makes it easy to add or remove the adapter and makes moving the adapter from one car to another simple.

The rubber tabs are firm enough to keep a full bottle secure even when making sharp turns, yet soft enough that your bottle is easy to remove when you want a drink.

The Swigzy adapter works great with many large fast food cups and most popular brands of water-bottles, including, but not limited to:

Hydro-Flask: 32 oz. and 40 oz.

Nalgene: 30 oz., 32 oz., 38 oz., and 48 oz.

Yeti Rambler: 20 oz., 26 oz., 30 oz., and 36 ounce (14oz. will NOT fit)

Klean Kanteen: 40 oz.

Camelbak: 32 oz. and 40 oz.

Takeya: 32 oz and 40 oz.

Important! Please Read:

Car cup holder design varies greatly. The adapter works with most car cup holders, but may not be compatible with certain styles of cup holders. Cup holders that have a unique shape, are next to the door, are angled sharply, have a cover that flips up or in, or are located where the dashboard hangs over the cup holder, may not be compatible. In vehicles with cup holders that are close together, the adapter may block access to the second cup holder.
