  • Great all around cooler backpack
Size: 35 Can Color: Black
This backpack is great! So many compartments. Plenty of room, and keeps everything cool all day with a couple ice packs.

  • Keeps everything cold and no leaks
Size: 35 Can Color: Orange
We've used this backpack cooler during a couple of Caribbean trips and have been very satisfied with the build quality. It holds plenty of drinks for a pool day and keeps everything cold. No leaks, either. Well-made product that I'd purchase again if I needed a 2nd one. Straps are comfortable, making it easy to carry even when fully-loaded. ... show more

  • Great purchase, well made
Size: 35 Can Color: Green
I bought this for my husband to take to work. He rides a Harley a lot and needed something he could transport back and forth with ease. Has so much room inside. He takes a 2 liter along with his lunch breakfast and snacks. It’s insulated and is made with a thick material that has held up well. It has so many pockets and a couple hidden ones. The bright color makes him easily seen when on his motorcycle. It has straps that buckle together in the front for added support that makes it comfortable to have on. ... show more

  • Solids choice and light weight
Size: 35 Can Color: Grey
Overall, great features. It’s lightweight, easy to carry, and has plenty of extra space and pockets for organizing snacks, cups and essentials. The design makes it convenient day trips, baseball and softball parks and the lake . Downside is that it does not hold key very well . If you are planning a longer outing or hot weather, you might find ice melts faster than expected . It works better with ice packs than loose ice . This is a solid choice with modification for ice . Enjoy the hot days with the family ! ... show more

  • Versatile, Spacious, and a Fantastic Value!
Size: 35 Can Color: Blue
I bought the Maelstrom Cooler Backpack as a wedding gift for my daughter and son-in-law, and I can confidently say it’s a winner because I personally own five Maelstrom coolers, including the backpack version in orange! I’m a huge fan of these soft-sided coolers—they’re incredibly versatile and perfect for camping, beach trips, hiking, or even shopping. The backpack design is a standout, holding a TON of items (easily 35-50 cans) while keeping contents relatively cool for a soft-sided cooler, which is impressive. The insulation also does a great job with water retention, keeping melted ice contained without any leaks during my trips, which is a big plus for messy outdoor settings. The adjustable padded straps make it super comfortable to carry, even when fully loaded, and the multiple compartments are great for organizing snacks, drinks, or utensils. The colors are vibrant and accurate to the description—I love the bright orange of mine! The quality is top-notch, with durable stitching and materials that feel built to last. For the price, this cooler backpack is an absolute steal, offering high-end functionality at a budget-friendly cost. My daughter and son-in-law are thrilled with it, and I highly recommend this cooler for anyone needing a reliable, spacious, leak-proof, and comfortable option for outdoor adventures or everyday use! ... show more

  • Initial impressions - not used yet
Size: 50 Can Color: Grey
Full disclosure - I have not used it yet, so this review is based on first impressions. The pack is well made and stitching is well done. The external material is heavy duty. Zippers are sturdy and well placed. Shoulder straps are nicely padded, and the lumbar support is good as I put some weight in it. The sternum strap is one of the many features that made me choose this cooler backpack. Most don't have them and when you load it up with ice and liquids the sternum strap sure relieves shoulder and lumbar strain. The insulation looks good and the interior fabric is heavy and will hopefully withstand abrasions. I will write a further review once I test it for leakage and ice retention. ... show more

  • Wish I’d found it sooner
Size: 35 Can Color: Orange
This thing is awesome! I’m so glad I bought it. It looks awesome, made out of great materials, zippers work great, great extra space. Enough room to pack a picnic. Comfortable to wear. So much better than a single-strap cooler. You can take it with you on a hike and things stay cold and protected.

  • Great for a Manual Laborer!
Size: 35 Can Color: Black
My hubby lays blacktop for a living, so we needed a cooler that could withstand the heat, and also fit all of his tools and other odds and ends since there's really not space to put multiple bags on his machine, and the car can be miles away. So first things first, yes. This backpack cooler does keep his food and drinks cold all day long, even being around hot asphalt all day. It's very well insulated. Next- This bag fits EVERYTHING! There are so many pockets and the zippers dont get caught! He uses the front pouch with the utensil slots to organize his tools. The top pouch fits his wallet, phone, and sunglasses. There's a secret pouch behind the lumbar padding that'll come in handy when we're in NYC. The padding on the shoulders and back is very thick, so it's not uncomfortable even when it's filled with a giant thermos, food, and tools. Can comfortably walk around with this all day long for hiking or urban exploration. BONUS- He's able to use the chest strap to secure the bag to the back of his seat while running the machine, so we no longer have to worry about it falling off! (His last cooler was a Milwaukee, and the strap broke and it got run over by the roller, crushing everything inside. And this has happened with at least 4 regular coolers over the years.) Overall, this Backpack cooler is extremely versatile. We plan to get a second one to use for camping, vacations, and just to have when we're planning to be out all day, just so he doesn't have to take all of his work stuff out of the one we already have. 1000% recommend! ... show more
