As a never-going-to-be-in-recovery Yeti addict, I have to admit, when I’m just running to a neighbor’s backyard party, I don’t bother filling up my large, heavy coolers. Instead, provided everything fits, I throw my drinks and food into an insulated lunchbox and it’s good to go. Unless you need ice to be kept for days, a lunchbox like this one is the best, most economical choice by far.
