I'm looking for a small cooler such as the one below for keeping things very cold for day long fishing trips. I usually fish in the hot weather and it gets into the 90'-100's in MN. So I'm just looking for a cooler that will keep my pop and water cold for a 4-7 hour fishing trip. I don't need anything too expensive or something that will keep ice for a week.
I have one like the one below but it doesn't even keep things cold for a few hours and that's when I put an ice pack in with it and it's in the shade under the console. I guess the one below doesn't have insulation in the lid and that's important.
So what's a good small cooler?
