Car Bottle Expander for Large Containers Up to 3.8 inches Wide

COMPATIBILITY Designed to be compatible with a range of popular bottles and mugs, including the Hydroflask 32/40 oz, 40 oz 50/50 Flask, and many others up to 3.8 inches in diameter. This cup holder adapter ensures a perfect fit for your needs.

SNUG FIT Say goodbye to rolling cups in shallow holders. Our cup holder for cars features a tapered, narrow base that narrows from 3.2 inches to 2.6 inches, providing a snug and secure fit. No more cups sliding around in your car.

RELIABLE HOLDING POWER Built to stay in place during turns and braking. The Hydroflask cup holder for cars is engineered with a 3-inch upper cup, ensuring your flask stays firmly in place. Other holders with smaller 2-inch upper cups are more prone to causing your bottle to fall out during motion.

DURABLE AND STurdy Crafted with ABS plastic for a glossy finish, ensuring resistance to impact and abrasion. This cup holder expander is designed to fit snugly into your existing cup holder, providing superior sturdiness for bottles and cups of all sizes during transit.

SMART DESIGN WITH SIDELINE SLOT The U-shaped cut-out on the side allows for secure placement of coffee cups or travel mugs with external handles. Start your journey with ease, knowing your favorite beverages or bottles are securely held with the smart cup holder-expander.
