Yeti Hopper Flip 18L Cooler Bag, Charcoal Grey, cool bag with shoulder strap

Yeti Hopper Flip series
The Hopper Flip series features soft cool bags with a tough zip and high insulation performance. They’re waterproof, lightweight and easy to carry with the shoulder strap, making them perfect for short day trips, picnics, or quick outdoor adventures. Ideal moments when a full cool box might be too bulky or inconvenient.

Dry Hide shell for extreme durability
Hopper Flip cool bags are built with a ‘Dry Hide’ shell; a high-density outer layer that’s resistant to UV rays, punctures and tears. Both the interior and exterior are treated to resist mildew. This makes the Hopper Flip not only incredibly durable, but also tough enough for daily use in demanding conditions.

Cold Cell insulation for top performance
Like Yeti’s larger cool boxes, the Hopper Flip series delivers impressive cooling performance. The ‘Cold Cell’ insulation is a closed-cell foam that retains cold far better than a standard soft cool bag. As a result, your snacks and drinks stay cold for hours, even on warm days.

Make the most of your Yeti cool bag
A cool bag doesn’t actively chill, it only retains the temperature of what you put in. That’s why good preparation is key. Pack the bag with pre-chilled items and add plenty of ice or ice packs. For best results, use a Yeti Thin Ice Pack, as these are specially designed to fit the bag perfectly. Air is your enemy! Keep the bag in the shade and open it as little as possible. Fill it up as much as you can: less air means better insulation. That way, your drinks and snacks will stay cold all day long.

100% leakproof and easy to use
Thanks to the ‘Hydro Lok’ zip, the Hopper Flip is completely leakproof. This rugged zip is built to withstand heavy use and keeps everything securely inside, even when the bag is full. The wide opening gives you a clear view of the contents and easy access to your stuff.

Easy to maintain
A Yeti cooler bag is easy to clean with a little warm water and detergent. Nice and easy! Always clean the cooler bag properly after use for optimal longevity.



About Yeti
Unlike their fictional namesake, Yeti products are the real deal. Yeti was founded in 2006 by brothers Roy and Ryan Seiders, born and raised outdoor enthusiasts. From a young age, they could be found on the water and in the field. They hunted, fished and travelled to outdoor trade shows with their father. What frustrated them time and again were the coolers they used on their travels. Handles broke, lids came loose and parts failed at the worst moments. They decided it could be done better. It had to be done better. No more throwaway products, but a no-nonsense cooler that could withstand anything. Driven by that mission, Yeti grew into a brand with a full range of durable gear, focused on food and drinkware. Made for outdoor lovers who don’t compromise. Designed to perform time and again, wherever you are.
