YETI Hopper Backpack M12 Cooler (Black Forest)

The YETI Hopper M12 Backpack Cooler is a premium soft cooler designed for hands-free carrying, making it ideal for beach days, hikes, fishing trips and picnics where portability matters just as much as cooling performance. In the Black Forest Green colourway, it combines a rugged outdoor look with YETI’s signature high-end finish.

Built with a durable waterproof shell and a high-performance insulated interior, the M12 is designed to keep ice and drinks cold for extended periods, even in warm conditions. It features YETI’s MagShield magnetic closure, which creates a wide-opening yet leak-resistant seal, making it easier to access contents compared to traditional zip coolers.

Despite its compact backpack design, it can hold up to 20 cans (without ice), making it perfect for 1–2 people or small day trips. It also includes a handy front pocket for small essentials like keys, phones or wallets, and a HitchPoint™ grid for attaching accessories.

Comfortable shoulder straps make it easy to carry when fully loaded, and the structured design helps it sit securely on your back during movement. It’s a popular choice for people who want a soft cooler that replaces bulky hard coolers for short outings without sacrificing performance.

Overall, the Hopper M12 is best suited for people who prioritise portability, quick access and premium insulation in a compact, adventure-ready format.
