I got a soft sided Yeti cooler for half off, had it for over 5 years now. It's good for track days and autox, holds just enough.

There may be better alternatives these days, Yeti's prices are crazy, but your basic igloo or whatever wouldn't keep stuff cool all day when it's really hot out. Yeti and similar cost a ton and don't hold much for their size, but they do keep your stuff cool. That's really the only reason to buy one.
