Hopper M Series Backpack Cooler - 36-Can Capacity, Magnetic Seal

Our review of the Hopper M Series Backpack Cooler finds it best for active day trippers, campers and tailgaters who want a hands-free cooler that actually keeps things cold. The single biggest reason to buy is reliable ice retention combined with a comfortable backpack form: it carries up to 36 cans or 22 lb of ice while distributing weight on your back, so it removes the need to haul a bulky hard cooler. The pack balances durability, insulation and usable storage into a design that feels built to last without unnecessary fuss.

Key Features

• 36-can capacity: Offers enough room for a full 12-pack plus extras or up to 22 lb of ice, making it useful for day trips and short overnight outings.
• MAGSHIELD ACCESS: Powerful magnets form an ultra-leak-resistant shield that stays open when loading and seals closed with a gentle push to limit leaks.
• COLDCell insulation: Closed-cell foam keeps internal temperatures low for extended periods so drinks and food stay cold longer.
• DRYHIDE shell: High-density fabric resists punctures and UV exposure, helping the backpack survive rough outdoor use.
• HitchPoint grid: Allows attachment of the SideKick Dry Gear Case or Molle accessories for extra utility on hikes or at camp.

Who It's For

The Hopper M Backpack is ideal for campers, hikers and event-goers who want the portability of a backpack combined with dependable cold-holding performance. Its 36-can capacity and 22 lb ice capability suit small groups or solo adventurers who need a day-to-night solution without a hard cooler.

Those who prefer a perfectly rigid cooler with longer multi-day ice retention or who need very large storage should look elsewhere; this soft-sided pack balances portability and insulation rather than maximal multi-day ice endurance.
