What Our Gearhead® Experts Are Saying:
"I love how the Hopper M12 Backpack Cooler keeps my drinks cold for hours on end, even on long summer hikes. It’s surprisingly lightweight for its capacity and fits snugly on my back without feeling bulky. The roll-top design is secure and easy to use, and the insulated body means ice retention isn’t an issue. Perfect for solo missions or sharing a cold brew at the summit."
We head out for a day of hiking, the YETI Hopper M12 Backpack Soft Cooler slung comfortably over our shoulders. With a design that’s as sleek as it is rugged, this packable powerhouse keeps us and our crew refreshed for miles.
The durable build of the Hopper M12 makes it a trusted companion, built to endure dusty trails, overgrown brush, and riverside stops. It’s lightweight yet roomy enough for up to 20 cans, and with a wine bottle-friendly interior, it’s equally at home at a lakeside picnic or an evening concert in the park.
Sturdy straps and a roll-top closure ensure an easy carry, while the waterproof construction and puncture-resistant material keep everything inside perfectly chilled. Whether we’re trekking up a mountain or setting up camp beside the water, this cooler has us covered from dawn till dusk.

Great for day trips!
Love, love, love my M12! I was worried about having a solid backpack that may be very heavy but the M12 was a perfect choice! Durable, heavy-duty material that will stand a beating from the elements for sure but not overly heavy or large for my needs. Chose this model over the zippered soft coolers because I wanted one tall enough that can hold an upright wine bottle. Flaps will stay open by itself and the magnetic closure holds well as long as the backpack is not overly stuffed. Already took it with me on a short beach hike as well as smuggled on a golf cart. Serves my needs perfectly to hold a few drinks and some food/snacks for the day. Also came with a chest strap to provide additional support when worn as a backpack which I greatly appreciate! Thank you Yeti for making an amazing product!

Not what I expected!
This cooler is extremely stiff, which I can work with, but it is really big to have such a small capacity for the contents. The directions say it needs to be full to keep things cold longer, and it recommends filling it 2/3 of the way with ice. I debated returning but decided to keep it and give it a try.

Pretty good....
I like the size (not too big) so when full, not hugging around too much yet I thought the magnets inside would be stronger per other reviews. Also the pocket in the front is so tight, I cant get anything inside it. But the ice rention was great! Thus i gave it a good rating.
