The YETI Hopper Cooler is over-engineered to keep ice for days.  Using materials found in things like survival suits, YETI has designed a cooler that is tough as nails - puncture resistant, leak proof and anti-microbial.

The Hopper is sized to fit any adventure, whether you're on a wild river in a kayak or in a floatplane on a remote salmon stream.  Easily transport at least 18 icy cans and keep them chilled for days.  DryhideTM shell,  Hydrolock zipper,  ColdCell insulattion.
