Because Sometimes the Trail Demands Both Hands.
There’s a moment, somewhere between the last cell signal and the first ridge of real solitude, when you realize just how much freedom lives in having nothing in your hands. No handles, no straps cutting across your palm — just you, the trail, and a pack on your back that carries cold like it was born to do it.
That pack is the YETI Hopper M20.
A marvel of soft-sided engineering, the M20 doesn’t simply ride along — it disappears behind you, distributing weight so effortlessly that 18 cans and a load of ice somehow feel like a mild suggestion rather than a burden. The MagShield Access opens wide with a pull, then snaps shut with the certainty of a steel trap. It keeps cold air in, warm air out, and leaves both your hands free for trekking poles, scrambling over boulders, or hoisting a kid onto your shoulders at the campsite.
Built with YETI’s signature toughness — waterproof exterior, puncture-resistant shell, and straps that look like they were designed for parachutists — the Hopper M20 is as comfortable navigating airport terminals as it is kayaking into hidden coves.
When you sling it on, you’re not just carrying refreshments. You’re carrying the promise that no matter how far you go, comfort is coming with you.

Frequently Asked Questions
What is a YETI Hopper M20 Backpack Cooler?
The YETI Hopper M20 is a soft-sided, backpack-style cooler designed for hands-free carrying and exceptional ice retention. It features YETI’s MagShield Access (a powerful magnetic closure), a waterproof DryHide shell, and comfortable ergonomic straps. It’s ideal for hiking, short trips, music festivals, kayaking, and any adventure where you need mobility and cold storage at the same time.
How long does the YETI Hopper M20 hold ice?
In typical real-world use, the Hopper M20 keeps ice for 20–30 hours, depending on outside temperature, how often it's opened, and how full it is. Packing it tight, using pre-chilled items, and minimizing warm-air exposure can extend its performance.
How do you clean a YETI Hopper M20?
Cleaning is quick and painless:
-
Rinse with warm water and mild soap.
-
Use a soft cloth or sponge for any buildup.
-
Rinse thoroughly to remove soap residue.
-
Let it air dry with the lid open.
Avoid bleach, abrasive cleaners, or tossing it into a washer — the M20 likes adventure, not abuse.
Where is the serial number on the YETI Hopper M20?
The serial number or lot code is typically found inside the cooler, often near the interior side wall or base. Look for a small printed or heat-pressed code. It’s intentionally subtle, but essential for warranty registration or product support.
