YETI Hopper M12 Backpack Cooler Classic Navy

What Our Gearhead(R) Experts Are Saying:"I took the Hopper M12 Backpack Cooler on a full day out, and it kept everything cold from morning until well into the afternoon without any fuss.

The MagShield closure is one of those details that sounds simple but makes a real difference in practice, snapping open with one hand and sealing back shut on its own.

The Kangaroo Pocket up front has become my go-to for keys and a card, so I am not digging through the main compartment every time I stop."The trailhead parking lot is full, and the lake is still a few miles out, which means cold drinks are a backpack problem and not a hand problem today.

The YETI Hopper M12 Backpack Cooler was designed specifically for that math, putting up to 20 cans worth of cold storage on your back in a slim, tapered profile that carries more like a daypack than a cooler.

Ergonomic straps distribute the weight evenly across the shoulders, double-stitched carry points handle the load at every pickup spot, and the whole thing moves through tight trails and crowded campsites without catching on anything.

ColdCell closed-cell foam insulation keeps interior temperatures well below ambient for hours, and a leakproof interior liner built with RF welding eliminates stitched seams that could eventually fail under pressure or temperature cycling.

The MagShield Access closure uses ultra-strong magnets to create a leak-resistant seal that stays open when you need it and snaps shut with a single push, no fumbling with buckles or zippers when your hands are full.

DryHide shell fabric resists punctures and UV exposure, while interior and exterior materials both carry mildew resistance for a cooler that lives in the field rather than the garage.

A Kangaroo Pocket on the front face keeps a phone, wallet, or keys accessible without opening the main compartment, and the HitchPoint Grid lets you clip on a Sidekick Dry, bottle sling, or any other YETI accessory without adding bulk to the carry.
