K2 Summit 20 cooler test.

I have the test. A simple one. Chill down cooler outside (recommended to do with ice before loading it down with food/drinks/ice), because its 20 degrees out. Fill half with snow. Put in garage. open it in 3 days (Saturday night/Sunday morning). Snow is much less dense than ice, but I think if there is any snow left or it's still cold, we're in business. This will be my long weekend/paddling/paddleboard trip cooler.
