The Yeti Hopper M20 Backpack Soft Cooler in Firefly Yellow is built for big days and bright energy. It’s the cooler you grab when you’re headed out before the sun’s fully up, when the plan includes miles, music, friends, and a whole lot of cold drinks. With its backpack design and rugged build, it doesn’t just tag along—it carries the day on its shoulders and keeps everything chilled while you focus on the fun.
Capacity is where the M20 starts showing off. It fits 36 cans, giving you plenty of room for a full crew’s worth of refreshments, and it fits 22 lbs of ice when you want to prioritize all-day cold retention. It’s also wine bottle compatible, which makes it a slick choice for picnics, lake dinners, beach sunsets, and any outing where you’d rather pack smarter than pack more. With dimensions of 15.3” w x 9.9” d x 18.1” h, it’s tall and efficient, so you can stack cans, stand bottles upright, and keep snacks from getting crushed. It rides like a pack, but it packs like a cooler that means business.
Inside, Coldcell insulation is doing the heavy lifting, helping your load stay colder longer even when the weather’s doing its best to melt your ice. Outside, the Dryhide shell brings the toughness Yeti’s known for—durable, abrasion-resistant, and ready for whatever the day throws at it. Toss it in the back of the truck, set it down on gravel, or squeeze past a crowded tailgate setup, and it’ll keep looking and performing like it was made for exactly that kind of use.
The M20’s Magshield access is the kind of feature you’ll appreciate every single time you open it. The opening is wide, so loading is fast and unloading doesn’t feel like a scavenger hunt. You can see what you’ve got, grab what you need, and get right back to what you’re doing. When you close it up, the seal feels secure and confidence-inspiring, helping keep cold air where it belongs and warm air out of your cooler.
And since it’s a backpack, comfort is the whole point. The ergonomic fit is designed to carry weight more naturally, so you’re not fighting a lopsided hand carry or giving up a free hand. At 89.6 oz., it’s a substantial piece of gear, but the way it rides makes it feel stable and manageable when it’s loaded with ice and drinks. Whether you’re hauling it down to the dock, trekking from the car to the campsite, or walking across the tailgate lot with chairs in one hand and snacks in the other, the M20 is designed to move with you.
The Hitchpoint grid adds a smart layer of versatility, giving you attachment points for the extras you always end up needing. Clip on add-ons, keep essentials accessible, and tailor your setup to the day’s plan without turning your hands into a juggling act.
And that Firefly Yellow finish? It’s loud in the best way—high-visibility, easy to spot in a pile of gear, and impossible to mistake for someone else’s cooler. It brings a little sunshine even when the forecast doesn’t.
