Freez Pak X-Large Extra Cold -2C Reusable Ice Pack with Hard Shell 4.7lbs

Was going to buy a more expensive name brand version from another store but it wouldn't arrive in time. I bought these and my they were delivered same day. I stuck them in my freezer for 24 hours and then loaded them into the bottom of my RTIC 65, laying down. I then loaded my cold beverages and ice on top of them. I was camping in May in North Florida with not enough shade. My cooler kept ice for longer than I've ever been used to. Despite lots of openings of the cooler, I still had some ice almost 3 days later. I did top it off one more time and these were partially frozen still 2 days later. I'd highly recommend these and I'm glad I saved money over the expensive cooler brand.

I didn't realize how huge this was until it came to my house! I recommend this size for an ice chest or if your love one has a huge lunch bag that works overtime. My husband told me sometimes theres no space for his lunch bag since the refrigerator at work is full. I highly recommend this product. Keeps your food and drinks cold!
