About This

✅ Universal Compatibility: EcoNour’s Cup Holder Expander is perfectly designed to hold popular 32 oz and 40 oz Hydro Flask bottles, 40 oz 50/50 flasks, and most tumblers and mugs with a base diameter of up to 3.8 inches. Whether you're commuting or road-tripping, this cup adapter keeps your favorite drink secure and within reach.
✅ Snug Fit for Shallow Holders: Tired of cup holders that are too shallow? Our expander features a tapered base (3.2" to 2.6") that ensures a tight and stable fit—even in compact or shallow car cup holders. Say goodbye to rattling or tipping during your drive.
✅ Enhanced Stability: Built to hold firm through turns, brakes, and bumps. Unlike standard models with a 2-inch upper cup, EcoNour’s holder features a 3-inch wide upper section to securely grip your bottle—minimizing the chances of spills or falls.
✅ Built to Last: Crafted from high-quality ABS plastic with a sleek, glossy finish, our cup holder adapter offers exceptional durability and impact resistance. Designed for long-term use, it delivers a clean, polished look while protecting your bottle.
✅ Smart Handle Slot Design: Includes a convenient U-shaped cut-out to accommodate cups or mugs with handles. Ideal for travel mugs, coffee cups, and handled tumblers—making it easy to carry your beverage of choice on the go.
