Yeti Hopper M12 Backpack Cooler

The magnetic closure is significantly easier to open and close, allowing you to access your drinks with one hand without wrestling with a stiff zipper. It snaps shut automatically to create a secure, leakproof seal, though you should still use the included buckles if you are hiking or transporting the cooler over rough terrain.

While 'days' is the technical rating, real-world performance depends on how often you open it and the ambient temperature. For a day trip or a long picnic, it will easily keep your contents ice-cold, but don't expect it to hold ice as long as a hard-sided, rotomolded cooler.

Yes, the straps are ergonomically designed and well-padded to distribute weight evenly across your shoulders. However, because it is a 12-liter capacity cooler, it can get heavy once filled with ice and beverages, so it is best suited for shorter hikes or walks rather than long-distance trekking.

The exterior grid is compatible with Yeti's MOLLE-style accessories, such as the Sidekick Dry gear case or bottle openers. It is designed to let you customize your setup so you can keep small essentials like keys, phones, or tools accessible without digging into the main compartment.

The DryHide shell is highly water-resistant and puncture-resistant, designed to withstand the rigors of outdoor use. While it will keep rain and splashes out, the cooler is not intended to be submerged in water.

The 12-liter capacity is compact, fitting roughly 20 cans of soda or beer without ice, or a smaller amount if you are packing ice and food containers. It is perfectly sized for a solo day trip or a couple's outing, but it won't hold enough for a large group gathering.
