I have the SoftPak 20 and it has been great, but has lived an easy life. Mine rides inside a pickup truck and occasionally on a tractor. BUT, my buddy has the same cooler and flew to Louisiana and back with it, and his looks really, really beat now. My zipper is fine, my buddy's is nearly broken. If it was hard use, I'd go Yeti. To save money, the Ozark Trail brand at Wal-Mart gets good marks for ice retention and value.
