Have a water bottle that doesn't fit in your car's cup holder? This is the product to solve your problems! The Cup Holder Adapter is an adjustable device that fits into your cup holder to hold larger size water bottles that wouldn't have fit before. This cup holder adapter is designed to work with 32 oz. and 40 oz. Hydroflasks, as well as other similarly sized water bottles.

There are two sizes:

• "Regular" which is designed to fit 32 oz. and 40 oz. Hydroflasks with nothing on them. The Regular size has an inner diameter of 3.75 in 
• "Silicone Boot" which has an added gap to fit bottles with the Silicone Boot. The 36 oz. YETI bottle will also fit in the Silicone Boot size. The Silicone Boot Size has an inner diameter of 3.85 in

This product was designed using a computer aided design program, then 3D printed on a high performance 3D printer. As a a result, layer lines from the manufacturing process are typically visible. To assemble your Cup Holder Adapter when you receive it, thread the lower and top parts of the Cup Holder Adapter together. To secure your Cup Holder Adapter to your cup holder, rotate the central spindle to expand the fingers, until the Cup Holder Adapter is tightly secured in place.
