Premium backpack cooler with revolutionary MagShield technology
What is the YETI Hopper M Series?
The YETI Hopper M Series represents the next evolution in portable cooling technology, combining the durability YETI is known for with innovative backpack design. This soft-sided cooler features the groundbreaking MagShield Access system, which uses powerful magnets instead of traditional zippers for effortless opening and closing. Designed for adventurers who refuse to compromise on ice retention or convenience, the Hopper M Series delivers professional-grade cooling performance in a comfortable, hands-free backpack format that's perfect for hiking, fishing, camping, or any outdoor activity where mobility matters.
Key Features and Performance
MagShield Access Technology
The revolutionary MagShield Access system eliminates the frustration of broken zippers and difficult closures. Ultra-strong magnets create a secure, leak-proof seal that opens with a simple pull and closes automatically. This magnetic closure system is not only more durable than traditional zippers but also provides superior insulation by maintaining consistent contact around the entire opening perimeter.
Ergonomic Backpack Design
The Hopper M Series features padded, adjustable shoulder straps and a breathable back panel that distributes weight evenly for all-day comfort. The backpack design keeps your hands free for hiking poles, fishing gear, or camera equipment while maintaining easy access to your cold beverages and food. Strategic padding and ventilation channels prevent overheating during extended wear.
Superior Insulation and Durability
Built with YETI's ColdCell Insulation technology, the Hopper M Series maintains ice for days, not hours. The closed-cell rubber foam provides exceptional thermal performance while remaining flexible and lightweight. The exterior shell is constructed from high-density fabric that resists punctures, abrasions, and UV damage, ensuring years of reliable performance in harsh outdoor conditions.
The interior features an antimicrobial liner that's easy to clean and prevents odor buildup. Multiple size options accommodate everything from day trips to extended expeditions, with capacities ranging from personal use to group adventures. External attachment points and daisy chains allow for additional gear mounting, making this cooler backpack a true outdoor workhorse.

Frequently Asked Questions
How long does ice last in the YETI Hopper M Series?
With proper pre-cooling and ice-to-contents ratio, the Hopper M Series can maintain ice for 2-3 days in moderate conditions. Performance varies based on ambient temperature, frequency of opening, and packing technique. Using a 2:1 ice-to-contents ratio and pre-cooling the cooler maximizes retention time.
Is the MagShield closure completely waterproof?
Yes, the MagShield Access creates a waterproof seal when properly closed. The magnetic system provides consistent pressure around the entire perimeter, preventing leaks even when the cooler is tilted or jostled during transport. The closure is also designed to resist opening under normal backpack movement.
What sizes are available in the Hopper M Series?
The Hopper M Series comes in multiple size configurations to suit different needs, typically ranging from 12-can capacity for day trips to larger options for extended adventures. Each size maintains the same MagShield technology and backpack comfort features while scaling storage capacity appropriately.
Can the backpack straps be removed for other carrying options?
The backpack straps are integrated into the cooler's design for maximum durability and weight distribution. While not removable, the design includes additional carrying handles and attachment points for versatile transport options when backpack carry isn't preferred.
How do you clean and maintain the Hopper M Series?
The antimicrobial interior liner wipes clean with mild soap and water. The magnetic closure should be kept clean and dry for optimal performance. The exterior fabric can be spot cleaned or hosed down as needed. Always ensure the cooler is completely dry before long-term storage to prevent mold or odor development.
