What is a tunnel pocket? Duffels/Backpacks etc have them.?

Question

I can find a Web site that has a picture of one. May bags by Under Armour say that they have a wet/dry tunnel packet to separate wet clothes from everything else, but not one site has a picture of what it looks like. Can anyone send me a link that shows what one looks like?

Answer 1

The tunnel pocket can be accessed from outside the bag. It is normally located at the bottom of the bag for slippers and the wet things.
