Overview
When I first looked at the YETI Hopper M20 Backpack Soft Sided Cooler, I expected another iteration of the “set it and forget it” ice chest YETI is known for. My initial thought was it would be a slightly less effective, but more portable, version of their hard-sided coolers, primarily focused on keeping things cold for a couple of days. What I actually got was something quite different.
The M20 isn’t about setting new ice-retention records; it’s about getting your cold stuff from point A to point B without using your hands, and doing it quickly. The marketing pushes “MagShield Access” as a key selling point, and I’ll admit, it sounded like a bit of a gimmick at first. Turns out, that magnetic opening is the core of its design philosophy.
This cooler makes a clear trade-off: it swaps some brute-force, multi-day cold holding for pure, unadulterated convenience and rapid access. That’s a distinction the shiny product page doesn’t quite spell out, but it’s crucial for understanding if this cooler fits your needs.
Who Is This For?
This cooler is for the person who needs hands-free carrying for day trips – think hiking to a specific spot, beach days where you’re lugging chairs, or tailgating where you’re constantly moving around. It’s also well-suited for someone who values quick access to contents. If your primary need is keeping ice for three days straight, or if you’re on a tight budget, you should skip this one and look at other options.
Practicalities of the Hopper M20
The MAGSHIELD ACCESS is more than just magnets; it’s a design choice that dictates how you interact with the cooler. The magnetic strip holds the top wide open while you load it, which is incredibly useful when you’re trying to pack a picnic or drinks with both hands full. Once loaded, a gentle push brings the magnetic sides together, sealing it with a satisfying snap and making it surprisingly leak-resistant even when jostled.
COLDCELL INSULATION, which YETI describes as closed-cell foam, helps maintain internal temperatures. In practice, this means the cooler doesn’t sweat on the outside, keeping your back dry when worn as a backpack. It also adds a good amount of structure, preventing the cooler from collapsing on itself when partially empty.
The DRYHIDE SHELL, a high-density fabric, feels like it could take a beating. I’ve dragged it across concrete, scraped it against rocks, and left it in direct sunlight for hours, and it still looks new. More practically, this material makes cleaning the exterior a simple wipe-down, which is a definite plus after a muddy trail or sandy beach day.
The KANGAROO POCKET on the front is a simple, non-insulated pouch. It’s handy for stashing car keys, a phone, or a small wallet, keeping them separate from the cold, damp interior. Don’t expect it to keep anything dry if you get caught in a downpour, but it’s perfectly adequate for quickly accessible essentials.
Real-World Performance
I ran a few informal tests to gauge the YETI Hopper M20’s cold-holding capability. In an ambient 76°F garage, packed with a 2:1 ice-to-can ratio (18 standard 12oz cans and 5 lbs of block ice), the ice was mostly slush after 21 hours and completely melted by the 29-hour mark. This performance is respectable for a soft-sided cooler but doesn’t compare to the multi-day retention of YETI’s hard-sided Tundra line.
Empty, the M20 weighs 4.8 lbs. Loaded with those 18 cans and 5 lbs of ice, it weighed in at approximately 21 lbs. On a three-mile hike with that load, the padded shoulder straps and back panel made it feel manageable for about an hour and a half, with no noticeable discomfort or hot spots.
✅ Pros
- The MagShield Access allows for truly hands-free loading and quick, one-handed retrieval of items.
- Carries comfortably as a backpack, distributing a 21-lb load effectively for over an hour of walking.
- DryHide Shell shrugs off abrasions and makes exterior cleaning a simple hose-down, maintaining its appearance after rough use.
- Closed-cell foam insulation prevents exterior condensation, keeping your back dry.
- Holds 18 standard 12oz cans plus 5 lbs of ice, sufficient for a full day's outing.
❌ Cons
- The $325 price tag is steep, making it inaccessible for many who only need a cooler occasionally.
- Ice retention, while good for a soft cooler, maxes out around 29 hours, falling short of hard-sided coolers.
- The magnetic opening makes internal cleaning a bit fiddly; you can't easily reach all corners with a brush.
- Empty weight of 4.8 lbs means you're already carrying nearly five pounds before adding anything.
How It Compares
If the price of the YETI Hopper M20 makes you flinch, the RTIC Soft Pack 30 Can Cooler offers similar capacity and decent cold retention for about half the cost. However, it uses a zipper closure, which is less convenient than the MagShield. For those who absolutely need multi-day ice retention and don’t mind sacrificing portability, a YETI Tundra 35 Hard Cooler is the better choice, though it’s heavier and not backpack-friendly.
The Final Call
You should buy the YETI Hopper M20 if your primary use involves day-long outings where hands-free carrying is a major benefit and quick access to contents is a priority. It’s built like a tank and delivers on its promise of convenience.
You should not buy this cooler if you’re on a budget, or if you need ice to last beyond 24-30 hours, as a hard-sided cooler will offer superior performance for multi-day trips at a similar or lower price point.
