One of the oddest descriptions I've seen for a piece of clothing...

[rozziland]

Imagine yourself below ground. Not in some trendy urban bunker that doubles up at as some ultra-chic, eco-friendly home, but literally down in the ground. Down with the moles in a world that is pitch black. All you can see, feel and taste is mud. Now imagine the day when you stick your little snout through the grass. Imagine the glorious colours and smells that greet you. Now buy one of these shirts and enjoy that same sensation.
