Kayak coolers

What are people using for coolers. I have been thinking of several options. I have an outback and would like to put it aft of my gear bag behind my seat. Has anyone seen a cooler that would work for fish and drinks... Two compartments? Soft coolers vs hard shell coolers? Has anyone put a yeti on their yak?
Any ideas

I have an old Coleman blue cooler that I'm looking at tearing apart and remaking myself for the back of my Revo. It's "insulated" - whatever that means but I'll be taking the liner out and super-insulating it with "Foam Stuff."

Heads up Bro. You should either contact the manufacture of Foam Stuff, and/or do some serious research about how safe of product it is for food storage. Not only if you're using it for an insulator for your fish storage cooler (where there's water and the temperature range fluctuates between semi-cool to barely safe enough for fish storage), but also if your keeping your personal consumables stored in it. Might be fine for sealed containers like beverage cans (no bottles on the water please), but you wouldn't want to find out a few days later or even years later some nasty chemicals had been leeching into your lunch....Just a thought
