YETI Hopper M Series Backpack Soft Sided Coolers - Hands Free Cold

In this review the YETI Hopper M Series Backpack is presented as a durable, hands-free soft cooler for active days outdoors; the single biggest reason to buy is its combination of strong cold retention and a backpack form factor that leaves your hands free. The pack carries up to 20 cans or 12 lb of ice and is built to hold that temperature with closed-cell ColdCell insulation, while the magnetic MagShield access keeps spills and leaks to a minimum. For anyone who needs a rugged cooler that travels on the back, this is a practical choice.

Key Features

• 20-can capacity: Fits up to 20 cans or about 12 lb of ice so it handles a day trip for two or a small group without bulk.
• MagShield access: Durable magnets form a leak-resistant shield that stays open for loading and snaps closed to reduce spills and speed access.
• ColdCell insulation: Closed-cell foam helps maintain low temperatures over time, keeping beverages and food colder for longer on multi-hour outings.
• DryHide shell: High-density outer fabric resists punctures and UV exposure, so the pack stands up to rough use at the beach or campsite.
• Kangaroo pocket: External pocket provides quick storage for a phone, keys, wallet, or small items you need to reach without opening the main compartment.

Who It's For

The Hopper M Series Backpack is aimed at hikers, beachgoers, and anyone who wants a serious soft-sided cooler that can be carried hands-free. Its 20-can capacity and robust insulation make it a good fit for day hikes, tailgates, or short camping trips where mobility and cold retention matter.

Those who need a massive multi-day cooler or one with rigid shelving should look elsewhere; this pack is optimized for portability and moderate capacity rather than the largest possible ice volume or long-term food storage for extended car camping.

Pros & Cons

• Durable DryHide shell and solid construction that customers report lasting for years.
