There would be no zipper to freeze, crack or break by using a drawstring tunnel entrance. Also, if you are getting lots of snow, it's easier to dig your way out of a tunnel door instead of trying to free zippers, etc. It will (in theory) save weight by not having a zipper door. And besides...no other tent will look like it and it's just so cool looking! :cool
