They are the real deal. Don't have one myself but my dad bought one down in FL this winter and it's awesome. He's got 2 yeti hard coolers and he likes the hopper better.
Zipper will never fail or freeze as its actually air proof, but they don't keep ice anything like the hard sided Yeti. They are tough as hell and nice to strap down to your ATV, but not super impressed by them like everything else they make. Price is not justified on the Hopper.
thanks guys... i'm looking for an aunt and uncle who need to keep a 12 or 18 cold for a day... i camp at their place and am looking for some type of "rent"...
