YETI Hopper M Series Backpack Cooler - 36-Can Capacity

Our review of the YETI Hopper M Series Backpack Soft Sided Cooler finds it best suited for day trippers and small-group outings who want robust insulation in a hands-free carry. The single biggest reason to buy is its balance of capacity and cold retention: it carries up to 36 cans or 22 lb of ice while the ColdCell insulation and DryHide shell preserve chilled contents for extended periods without becoming a bulky hard cooler.

Key Features

• 36-can capacity: Packs enough beverages for a day trip or picnic while keeping the pack comfortable to carry on trails or around town.
• MAGSHIELD ACCESS: Powerful magnets create an ultra-leak-resistant seal that stays open when loading and seals with a gentle push to prevent spills.
• ColdCell insulation: Closed-cell foam helps maintain low temperatures so ice and cans stay cold through a long day.
• DryHide shell: High-density fabric resists punctures and UV exposure to stand up to outdoor use and rough handling.
• HitchPoint Grid: Modular attachment points let you clip on a SideKick Dry Gear Case, bottle opener, or multi-tool for quick access.

Who It's For

The Hopper M Backpack is ideal for campers, hikers and tailgaters who need a mid-size soft cooler they can carry comfortably while keeping hands free. Its capacity and insulation fit well for day hikes, beach days, or a small group gathering where mobility matters as much as cold-holding.

Those who want a rigid, long-term ice locker for multi-day car camping or who require an ultra-light ultraminimal pack may want to look elsewhere; the Hopper prioritizes insulation and durability over minimal weight or fridge-like multi-day performance.

Pros & Cons
