  • 15 L Soft Cooler Pack is rated 4.9 out of 5 by 47.
    Rated 5 out of 5 by from Great Backpack cooler I bought this a month ago and took it to the beach. Kept beverages cold with a small amount of ice. Easy to carry on back while riding a bicycle. The hands free is priceless! Another great feature is the dry pocket on the lid and the fact that the cooler stands up without falling over. Go on and get this, you won’t regret it.

    Rated 5 out of 5 by from I love this cooler!! This cooler is amazing!!! The backpack design of it (with front chest snaps) is so comfortable and easy to carry. I packed a lunch to take camping with 3 ice packs, 2 cans of soda, 4 bottles of water, 4 sandwiches, container of tomatoes, cucumbers, salad dressing, and snacks in pockets. It was easy to carry the food, and the next day....well after 24 hours, drinks were stilled chilled. It is very easy to clean out too. Just wipe it down leave it to dry.

    Rated 5 out of 5 by from Very sturdy. Keeps cold Tried this for about a month so far. Solidly constructed. Zippers very smooth. Keeps food and drinks cold for a long time even after being in a hot car for a couple hours. Has small compartments for extra storage or small items. Also a pocket in one side for a drink bottle. Definatly love it. One of the best soft coolers I've used.

    Rated 5 out of 5 by from Amazing quality I bought this Cooler since I travel often and it requires me to pack food. This cooler is lightweight, durable and easy to clean. Food items stay cold a fresh for a long time so I have no worry that my food will spoil. The backpack straps make it convenient to transport no matter where I am. I love this cooler.

    Rated 5 out of 5 by from Great features and priced better, too. This soft side cooler has straps for use as a backpack. Perfect for camping, going to the lake, or tailgating. It keeps items cold for more than 24 hours. It has a separate top for something flat and a side pocket for your cell phone. Very cool.

    Rated 5 out of 5 by from Great Soft Cooler Pack - Beach, Boat, Backpacking We love this Hydro Flask 15 Liter Soft Cooler Pack. The backpack cooler option allows you to take this just about anywhere including the beach, the boat or hiking in the woods. The cooler is well insulated to keep all of your drinks and foods cold and the zippers are heavy duty. Additional pockets and loops are very convenient and the backpack straps make hauling your load a breeze as they are very comfortable. The black color choice looks more like a deep charcoal grey to me.

    Rated 5 out of 5 by from Great for on-the-go needs! This cooler is the perfect size and form factor for those outings where you just want to bring some cold drinks and snacks - great for a family day trip. We often want to carry cold cans of sparkling waters when we travel, especially during hot texas summers (we sometimes just take a cooler of waters for days of running errands since it gets so hot out!) and this makes it easy! Love that you can wear it like a backpack and nothing leaks, etc.

    Rated 5 out of 5 by from Obsessed! This cooler backpack is amazing! It holds the perfect amount and isn’t too heavy so I’m still able to carry it! I’m a small woman who hasn’t had any issue getting It around. The backpack straps are also very padded and comfortable. It keeps all of the contents cold and holds ice great! It did have a little bit of a plastic smell to it right when it was unboxed, but that went away after a day.

    Rated 5 out of 5 by from Great cooler! I love my Hydro Flask 15L Soft Cooler Pack! First time I used it was on a hike in the woods with the kids. I love that I can have the cooler on my back . It’s comfortable and my back doesn’t hurt. The cooler kept everything nice and cold . We have used it for an 8 hour road trip and I put a few ice packs in the cooler along with my things that needed to be refrigerated and kept cold . The ice packs were still ice! I have put a few ice packs in my cooler and used for grocery shopping to keep my frozen , frozen. Then put on my back to carry in the house . The cooler is made high quality and has little pockets to put your personals for hiking ,camping , taking to the beach or lake . We plan on getting a lot of use out of it in the summer for the beach! I highly recommend getting the Hydro Flask 15 L Soft Cooler Pack, so many ways and places to use it.oh and the cooler does not leak!

    Rated 5 out of 5 by from Amazing cooler! Impressed with this cooler! Don't let the size fool you. It is compact but very spacious. It is durable enough to last years and easy to clean. My favorite part is the lightweight no matter what I have in it compared to most coolers of same size. I also love that it keeps all cold for at least 24 hours which is great. I finally have the perfect cooler that I can take with me on bike, hiking, picnicking, in car, etc. Try it! You won't be disappointed. I highly recommend.

    Rated 5 out of 5 by from Nice cooler backpack! I enjoy having picnics outdoors and this cooler pack is ideal for that! The size of this cooler pack is great as it can fit a considerable amount of food and drink, and fits wine bottles vertically!! The pack is light and the straps are comfortable. It has a chest strap so that it does not bounce around while hiking. Although it is soft, it does not fold flat because it has a semi-rigid structure. As for insulation it works pretty well for 24 hours.

    Rated 5 out of 5 by from Wow. Just wow. This was my first semi-large soft cooler. I might never go back. It’s strap makes it so easy to transport, and I took it via bicycle to a multiple hour tailgate... everything stayed cool no problem! Huge fan!!!

    Rated 5 out of 5 by from Great Features! I received my Hydro Flask 15 L Soft Cooler and was so anxious to give it a try. I took the cooler to a family picnic and liked that it is a soft-sided cooler which was so much easier to transport than the basic hard-sided coolers. It kept my beverages cold for a long time and I liked the fact that it lightweight, durable and waterproof. Some of the great features are the easy access top for filling and for cleaning, the comfortable carrying straps and I also like the extra storage in the top and in the side pocket. I would definitely recommend this cooler to anyone looking for a quality product.

    Rated 5 out of 5 by from Really keeps cold This cooler really does keep things cool for about 48 hours. Take a road trip with cooled drinks, meats and cheese and a cold/freezer pack and all goes well. The “back pack straps make it easy to transport for kids soccer/football games or hiking.

    Rated 5 out of 5 by from Roomy lightweight cooler that's easy to carry This cooler is just what I needed, its nice and roomy and lightweight so its easy to carry as well. I love how its so easy to clean as well, you just wipe it clean with a wet cloth and it's clean and looking like new. I take this cooler to my son's football games and it keeps our drinks and snacks nice and cold like I just grabbed them out of the fridge. This cooler has a special bottom that allows it to stand up on its own which is really handy when I'm getting stuff out of it or packing it. There's also pockets on the top and sides for keeping smaller items cold. This cooler is so roomy too I can get plenty of cans or bottled drinks and still have room for a lunch or snacks. This is my first time using a backpack cooler and I absolutely love it. No more dragging or lugging a heavy cooler to our spot, now I can just throw it on my back leaving my hands free to use. The straps on the back are padded too so they're comfortable on my shoulders and don't dig into my skin. The straps also adjust to fit where you want to wear it on your back. And best of all there's a strap that goes around your waist and clips so I can secure the cooler to my back fully. This is quite helpful if you want to take this cooler when on a hike or cycling. My husband owns a motorcycle and we sometimes take rides together and go site seeing and I love how I can pack a lunch and put it in the cooler and carry it on my back on the ride and be comfortable.

    Rated 5 out of 5 by from Frigid! Can’t say enough good about this cooler! From a performance aspect it has exceeded my expectations. Tested it out the first night and ice packs were still frozen solid the next morning (our house was around 74 degrees). When we pack it with other cold/frozen items it has no problem staying cold for well over a day. Zippers are waterproof too so no water leaking out the zipper. The interior of the cooler is lined with extremely durable plastic. Have no issues with punctures to the liner. Exterior fabric is durable and the bottom of the cooler is nicely lined with a plastic coating to keep the bottom from getting dirty. Multiple exterior pockets and zippered pockets to keep all your other belongings safe. My favorite feature is the backpack straps. We use this frequently when out with our kids and really appreciate that it lets us have 2 hands free. The best performing soft side cooler I’ve ever used! Love this cooler!

    Rated 5 out of 5 by from Keeps drinks COLD! Very portable! I got this a few weeks ago and couldn't wait to try it out. I have other Hydro Flask products and they've performed very well and held up really well. This cooler pack is exactly the same. It's ergonomically correct and never hurts my back, even when full. It does a great job in keeping everything cold and fresh!
