    • Definitely worth the money!

This is an awesome bag. I use it daily as a merchandiser for all my cokes and waters. It’s perfect for that. Keeps my drinks cold all day. I worked 12 hour shifts. It’s amazing being a backpack makes it so easy to transport to my and back into my house versus having a huge plastic cooler. This is so much better than my cheap Amazon backpack. It never leaks when it tips over. Overall, if you’re considering a backpack for work, get this or the small variant depend depending on how many drinks you need during the day. It pairs perfect with the yeti 3l bag for my tape and battery back up and gloves that I need for my work! ... show more

    • YETI Hopper M Series Backpack Cooler: A Stylish and Durable Choice
Style: M20 Color: King Crab
I'm absolutely in love with my YETI Hopper M Series Backpack Cooler! The color is stunning, and the size is perfect for carrying my drinks and snacks on outdoor adventures. One of the standout features is the MagShield Access, which makes it incredibly easy to open and close the cooler. The durable construction and high-quality insulation keep my drinks ice cold for hours, even in the hottest weather. The backpack design is comfortable to wear, and the straps are adjustable for a perfect fit. I love that I can carry it on my back and have my hands free to enjoy my activities. If you're looking for a stylish and durable cooler that can keep your drinks cold all day long, I highly recommend the YETI Hopper M Series Backpack Cooler. It's a fantastic investment for anyone who loves spending time outdoors. ... show more

    • Can't go wrong with Yeti!
Style: M20 Color: Charcoal
Love this cooler. It is insulated well. 30 cans is great storage size. Leak resistance. Anything Yeti is great quality. Even ordered the dry bag to attach for our main use of this will be on the raft. Easy to carry to river and will be easy to attach to our boat.

    • What a game changer!
Style: M12 Color: Big Wave Blue
After using this on several occasions such as trips to the water park, zoo, hiking, and grocery hauls, I can say that these Hopper series backpacks are seriously worth the money. Sturdy build quality! Fell off of a moving pickup around 20 mph onto the pavement and not so much as a scratch on it. Also found out on that same occasion that it does not leak! Kept our beverages and frozen burger patties solid for about 5 hours (with ice). Space is limited, but that's what full sized coolers are for. It can be tricky getting larger items like milk gallons through the opening, which is stiff and can be difficult for some to fold over and close using the buckles. The only real way to dry it out is to place it upside down while open to properly drain and air dry. All in all, worth every penny if you want a durable backpack cooler if you're on the move to keep your hands free and drinks cold. The dry bags made by Yeti also mount nicely to this cooler and are a handy place to keep your phones/wallets as well. ... show more

The Yeti Hopper M Series is incredibly durable! My husband uses it everyday! Keeps drinks cold for hours and the Magshield opening makes access super easy. Perfect for day trips, tailgates, and the beach. The backpack strap lets you be hands free to carry other things. Anyone looking for a tough, reliable soft cooler look no further. ... show more

    • Just received this Yeti Cooler
Style: M20 Color: Big Wave Blue
The bag is really nice. I have not used it yet (July 2025). When you get this bag it is important to let it air out. It smells really strong of chemicals, that is the only reason for removing one star. Once that is done it is great. The seams and straps seem to be very sturdy and the closing system at the top is secure with both the magnets and the buckles. The shoulder straps extend far enough to be comfortable for most size people. I have the blue color and it is a vibrant blue that is fantastic to look at and hard to lose. ... show more
