Review on CleverMade Insulated Reusable Ice Pack for Optimal Cooling by Joel Young

I really like these. They are amazing. I appreciate them because you get a nice multipack that's light, small and easy to store away until you need it. You can make one or more packs to use and store in the freezer. Then you have spare parts on hand in case one of them wears out or fails at some point. Or if you just need more. The cork and lid design is great for sealing the package after filling with water. This will most likely be the backpack's point of failure, but it is solidly built and feels very solid. Compared to regular sealed ice packs, you have packaging with a hard plastic lid. I found the lid doesn't get in the way, and as a bonus, it's a less-chilly place to grab a backpack. This allows it to wear out faster due to the stress on the lid area, but I tend to hold it by the lid more often when taking it out of the freezer. If you have a CleverMade cooler, this would be a good addition. Works in both hard and soft coolers. 5 stars for quality, innovation and value.
