When I first saw this feature I wondered the same thing.  Lately
I've been working on heating and cooling ductwork, so I've been
thinking about it.  Yesterday while preflighting the Warrior
I rent, I paid special attention to the cooler.
The Warrior has the same cooler that we buy from Velocity.  There
was cotton rope (I think that's the word for it) pressed into
all the grooves on the cooler.

Why couldn't they build it without being leaky?
