Xspander™

Xspander: Universal Cup Holder Adapter for Cars, Boats & Golf Carts What is the Stupid Xspander™? The Xspander is a rugged cup holder adapter that transforms standard, tiny cup holders into secure spots for large bottles. Whether you are in a car, boat, golf cart, or RV, this adapter twists to lock into place, ensuring your 40oz hydro-vessel doesn't fly across the cabin. Why You Need It: Universal Compatibility: Works anywhere you have a standard cup holder—cars, trucks, boats, home theater seats, and golf carts. Fits the Big Brands: Specifically designed to hold Yeti, Hydroflask, Nalgene, Stanley, and other wide-base bottles (up to 4.25" wide). Twist-to-Lock Security: The base expands to grip the walls of your existing cup holder, so it won't wobble or pull out when you lift your drink. The "Stupid" Details: Factory cup holders were designed for 12oz sodas in 1995. We fixed them. Durable Construction: Built tough to withstand daily commutes and choppy waters. Design: Simple, stylish black finish that blends into your console. Convenience: Stop holding your water bottle between your legs. (We know you do it.)
