The Ocean Spray bottles frozen and placed in the bottom of the cooler put the food or drink on top and then ice on top of that.
The solid ice will keep everything in the cooler colder longer.
There was a thread on here about making DIY PVC ones... I made a few and they seem to work great. I used 2 inch PVC the length of a Yeti roadie... 2 or 3 of them keep everything cold for the day and you get little to no water in the cooler so clean up is a breeze...
My wife orders those "Hello Fresh" meals and they come with that re-useable gel. The packages are about 8x12 inches and lay flat in the freezer. When we need one, we pull it out and put in bottom of the YETI. If they bust, we just throw them away. My Dad swears by the 3 liter bottles filled with water and frozen, but they take up too much space.

Ditto. Then when they started leaking, which doen't take too long, I cut the corner off and pour that goo in to plastic bottles or pvc tubes made to fit your cooler. It's prolly the same stuff as cooler-gel mix. Works good!
